  7. The Central Challenge The Intent of the Challenge: • The team must build a Structure made entirely of materials chosen from a list (see Section A.3). • A “Bill of Materials” (BOM) used to build the Structure will be created and included in the team’s paperwork. • The team must test the Structure’s strength at the tournament by placing weights on it and by subjecting it to Ram impacts at a marked corner of the Pressure Board that will cause a twisting force. • The team must create a Story which includes an unexpected event or twist. • Additionally, the team must build a prop or costume using only all the same materials used in the Structure.

  8. Team Choice Elements • In addition, the team must present TWO creations called “Team Choice Elements” that show off their interests, skills, areas of strength, and talents. • The team may create anything they wish for Team Choice Elements including props, music, technical gadgets, costumes, physical actions etc.

  9. The Presentation Site • The minimum dimensions of the Presentation Site will be 16ft x 16ft (4.88m x 4.88m). In most cases, this area will not be marked on the floor. When possible, the tournament may provide a larger Presentation Site. The team may use all of the Presentation space available at their site, but they must be prepared to present in the minimum area specified. The team should keep in mind that the weights, Structure Tester, and Ram will occupy a portion of the Presentation Site. • The team must not move the Structure Tester from its location. • A single 3-prong AC electrical outlet will be provided at least to the edge of the Presentation Site.

  16. A. Central Challenge - Section 1 Intent of the Challenge: • The team must build a Structure made entirely of materials chosen from a list (see Section A.3). • A “Bill of Materials” (BOM) used to build the Structure will be created and included in the team’s paperwork. • The team must test the Structure’s strength at the tournament by placing weights on it and by subjecting it to Ram impacts at a marked corner of the Pressure Board that will cause a twisting force. • The team must create a Story which includes an unexpected event or twist. • Additionally, the team must build a prop or costume using only all the same materials used in the Structure.

  17. Questions for Appraiser Training Challenge E: Twist-O-Rama 1. The team arrives in the Check-In area with a Structure, but no Bill of Materials or material samples. What should the Check-In Appraisers do? 2. The team arrives in the Check-In area with a Structure, but the BOM and/or the materials samples do not match the materials used in the Structure. What should the Check-In Appraisers do? 3. The team arrives in the Check-In area with a Structure, BOM, and materials samples. However, one, more, or even all of the materials listed on the BOM are not directly recognizable in the composition of the Structure. What should the Check-In Appraisers do?

  18. Questions for Appraiser Training Challenge E: Twist-O-Rama 1. The Check-In Appraisers should review with the team the Challenge requirements (A.3.b.ii) that state a Bill of Materials and materials samples must be provided. They should further explain the points at risk in not fulfilling the requirement. If time permits, they should allow the team to create the BOM and produce material samples. If the team fails to provide an accurate BOM and valid material samples, they should receive a 0 for C.3. 2. There are a couple of possibilities here. If the Structure is eligible for weight score, the Check-In Appraisers should point out the discrepancy, explain the points at risk, and allow the team to create the Bill of Materials and produce material samples. However, if the Structure does not pass, the Appraisers should give the team the opportunity to make changes to the Structure. The Appraisers should remind the team that in order to get the 10 points for the BOM and materials samples, the modified Structure may require a modified BOM.

  19. Questions for Appraiser Training Challenge E: Twist-O-Rama 3. The Check-In Appraisers should ask the team how they built the Structure and why the materials are not recognizable. If the team has a plausible explanation, the Structure should be passed and marked eligible for weight score. The Appraisers may need to mark the “Yes – Structure to be returned to Check-In” box in order to take a better look after the Presentation.

  20. Questions for Appraiser Training Challenge E: Twist-O-Rama 4. An Elementary Level team arrives in the Check-In area with a Structure that only contains two different materials, e.g. only Bamboo and Glue. What should the Check-In Appraisers do? 5. A Secondary Level team arrives in the Check-In area with a Structure that contains five different materials, but two of the materials are tiny pieces merely added to the Structure and they do nothing to help the Structure support weight. What should the Check-In Appraisers do? 6. The team arrives in the Prep Area without a Bill of Materials. What should the Prep Area Appraiser do? 7. In reviewing the Tournament Data Form, Page 2 Part THREE 2b, the Prep Area Appraiser really does not understand what the surprise or twist is supposed to be. What should the Prep Area Appraiser do?

  21. Questions for Appraiser Training Challenge E: Twist-O-Rama 4. The Check-In Appraisers should review with the team the Challenge requirements (A.3.a.i) that state Elementary Level teams must use at least three Materials. The team should retreat to attempt to modify their Structure to meet this requirement. When they return, the Check-In process starts again from the start. 5. Assuming there are no other issues, the Structure should be passed. The Challenge does not require any Material to be weight bearing or appear in any minimum quantity.

  22. Questions for Appraiser Training Challenge E: Twist-O-Rama 6. The Challenge (A.7.b) requires that one prop or costume must be built of the same material types as the Structure. In addition, the team is required to create a BOM that lists the material types used in the Structure. However, the Challenge does not state that the team must provide a copy of the BOM at the Prep Area. The Prep Area Appraiser will have to evaluate the validity of the materials used in the prop or costume by observation. 7. The Prep Area Appraiser should ask the team for an explanation. The purpose of the Tournament Data Form is to provide guidance to the Appraisers. If the Prep Area Appraiser does not understand the team’s TDF, there is a high probability that the scoring Appraisers will not understand either. Have the team attempt to improve their TDF while still in the Prep Area.

  23. A. Central Challenge – Section 2 2. Designing and Building the Structure: • The team must design and build a Structure, made only of materials chosen from a specific list (see Section A.3), that will be tested at the tournament.Teams are encouraged to build and test many structures before they come to the tournament. • The team must design the Structure so that they can place it on the Structure Tester at the tournament for testing. The team will test how much weight the Structure can hold by stacking a Pressure Board and weights on it (Section D.4.a shows a diagram of a Structure Tester), while at the same time subjecting it to off-center torque and twist-inducing impacts. • Team members must do all tooling and/or shaping of the materials chosen.

  24. A. Central Challenge – Section 2 • The team must not use any type of technology that designs, creates or aids in the testing of the Structure based on input of the Challenge specifications such as Computer Aided Design (CAD) or Structural Analysis Systems. The team must make any Jig(s) (see definition) used to construct the Structure.

  25. A. Central Challenge – Section 3 • Structure Specifications: • a. The Structure must be made entirely of materials listed below. • Elementary Level teams must use at least three (3) Materials. Middle Level teams must use at least four (4) Materials.Secondary/College & University Level teams must use at least five (5) Materials. • Only materials from the Structure Materials List below may be used: Aluminum Foil: Commercially available Aluminum Foil sold in rolls or sheets from which pieces can be cut. Aluminum Foil that is less than or equal to 200 micrometers (0.008in) in thickness is acceptable. Most regular and heavy-duty Aluminum Foil available in retail stores meets these requirements. Aluminum foil tape is not allowed. Bamboo: Any of the various woody perennial evergreens of the true grass family. Copper Wire – 16 gauge (1.29 mm) or smaller, uncoated: Wire made from elemental copper. Cork: The natural outer tissue of the Cork Oak, used to make stoppers or cork board/sheets. Corrugated Cardboard – 3/16in (4.5 mm) thick or less: Commercially available material used for boxes, made from wood pulp, formed of three layers: two flat outer layers, with an internal pleated (or fluted) layer

  26. A. Central Challenge – Section 3 Duct Tape: Grey, Silver, or any commercially available color, fabric based adhesive tape 1.88in (48mm) wide. Example: 3M UTILITY (#1900) Duct Tape. Glue: Any commercially available adhesive material applied in a liquid form capable of creating a permanent bond - e.g. two part epoxy, Gorilla Glue, super glues, wood glue, hot glue, glues that use an accelerant, etc. Hook-and-Loop fastener: Commercially available fabric-based hook-and-loop material. Monofilament Fishing Line: Any commercially available single-strand non-metallic fishing line, of any weight or diameter. Newsprint: A low-grade machine-finished printed (either black and white or color) paper made from wood pulp, used chiefly for newspapers. Latex-Free Balloons: Commercially available non-porous elastic rubber bags capable of being inflated. (Original packaging must be provided.) Latex-Free Rubber Bands – Thickness/Width: 1/32in to 1/8in (0.75mm to 3.0mm); Loop Length: 1in – 6in (25 mm – 150mm) or 2in – 12in (50mm – 300mm) opened loop length: A commercially available continuous loop of rubber, used to hold items together. (Original packaging must be provided.) Pasta: A food product made primarily from flour. Examples would include spaghetti, lasagna, fettuccini, macaroni, and noodles.

  27. A. Central Challenge – Section 3 Plastic Drinking/Stirring Straws – ¼in (6 mm) in diameter or smaller: Commercially available thin tubes of plastic (such as polypropylene and polystyrene) used for stirring liquids and/or transferring them from a container to the mouth of a drinker by use of suction. Plastic Toothpicks – 3in (75mm) long or smaller: A pointed plastic instrument used for removing food particles from the teeth. Plastic Trash Bags - 33 gallon size or smaller: Commercially available non-porous plastic bags used for the purpose of holding trash. Playing Cards: Any type of card commercially available in multiple quantities called a “deck,” typically used in playing a game or games of any type. Index cards, cards cut from materials such as poster board, boxes, and the like are not considered Playing Cards. Twist Ties – Paper or plastic wrapped wire, 4in (100mm) or less in length: Paper or plastic wrapped lengths of wire available in supermarkets and used as a bag closure. iii. Natural wood and products made from natural wood CANNOT be used in the Structure or in the scored prop/costume (see A.7.b). Natural wood is a substance found under the bark of any type of tree. Products made from natural wood such as plywood, Masonite, and fiberboard or chipboard are also NOT acceptable

  28. A. Central Challenge – Section 3 iv. The team may join materials together in any fashion. v. Teams must not melt any materials except Glue for use in their Structure. vi. Incidental marks – pencil or ink – are allowed. b. The team must create a Bill of Materials (BOM) used, and samples of those materials must be provided. i. Appraisers will inspect the materials used in the Structure during Structure Check-In (See D.2) and make sure that they correspond to those listed in the BOM. If necessary, the Appraisers will examine the materials again after the team tests the Structure. ii. The team will receive points for providing a Bill of Materials and samples of the materials. • c. The team will be asked to describe their Structure and tell why they chose the various materials. The team’s design will be appraised on how creatively the multiple materials were included and used.

  29. A. Central Challenge – Section 3 • Weight of the Structure: The total weight of the Structure must not exceed 175 grams. • Height of the Structure: The height of the Structure must be at least 7.5in (19.1cm) and no more than 9.0in (22.9cm). • The Structure must be a single unit. Multiple free-standing pieces placed on the Structure Tester will not meet the Challenge requirements. • The Structure must fit on the Structure Tester. (See D.4) • An opening that can easily accept a circular column with an outside diameter of 2in (5.1cm) MUST run the entire height of the Structure. This ensures that the Structure will fit easily around the Safety Pole of the Structure Tester, but not through the hole in the Pressure Board. • When the Structure sits on the Tester Base, it must fit completely within the Tester Base and around the Safety Pole. • The only places the Structure may make contact with the Structure Tester are the top surface of the Tester Base, the bottom surface of the Pressure Board, and the Safety Pole.

  30. A. Central Challenge – Section 4 • Weight Held Measurement Procedure: • After the Presentation time begins, the team will place the Structure over the Safety Pole so that the Structure rests only on the Tester Base. The Structure may touch the Safety Pole. • The team may start Weight Placement at any time once the Presentation time begins. (See D.4 for Weight Placement details.) • The team begins Weight Placement by placing the Pressure Board on the Structure. • After the Pressure Board is placed, the team must deliver an impact to the corner of the Pressure Board using the Ram (see Section A.5). The team will receive a 50 pound Bonus Card if their Structure successfully survives the Ram impact. This card is placed by a team member on top of the Pressure Board. • Each time a total of 45 or more pounds of weight is successfully added to the Tester weight stack, the team must deliver another impact to the marked corner of the Pressure Board using the Ram. The team will receive a 50 pound Bonus Card each time their Structure successfully survives a Ram impact. This card is placed by a team member on top of the weight stack. • After each Ram impact, the 45 pound “count” begins again. No weight amount “carries over” from prior loading. Example: After the Pressure Board is placed, a Ram impact is required. Next, if 45 or more pounds are loaded on the Tester (one 45 pound weight, or two 25 pound weights, or a 25 pound and two 10 pound weights, etc.) another Ram impact is required. When 45 or more pounds is again loaded after this impact, another Ram impact is required.

  31. Questions for Appraiser Training Challenge E: Twist-O-Rama 8. Since the last Ram Impact Bonus, the team has placed 10, 5, 10, and 5 pound weights. The team then places a 45 pound weight, for an incremental addition of 75 pounds. What should the Weight Placement Appraiser do? 9. Since the last Ram Impact Bonus, the team has placed 10, 5, 10, 5, and 10 pound weights. The team then moves the Ram from the Ram Box and begins to line up the Ram with the Pressure Board. What should the Weight Placement Appraiser do?

  32. Questions for Appraiser Training Challenge E: Twist-O-Rama 8. The Weight Placement Appraiser should announce that a Ram Impact is required. The Challenge (A.5.b) states that a Ram Impact is required once the team has placed 45 pounds or more on the Tester weight stack. The 30 pounds previously placed did not reach the 45 pound threshold, but adding the 45 pound weight certainly did. 9. The Challenge (A.5.b) states that the Weight Placement Appraiser determines when a Ram Impact is required. Also, the Challenge (D.7.b) states that the Weight Placement Appraisers will inform the team when a Ram Impact is required.Therefore, the team should not attempt a Ram Impact unless the Weight Placement Appraiser has announced “Ram Impact required.” In this case, the team has not reached the 45 pound threshold and should not yet be attempting a Ram Impact. The Weight Placement Appraiser is not obligated to stop the team from performing a Ram Impact, but cannot grant a Bonus even if the Ram Impact is otherwise successful.

  33. A. Central Challenge – Section 4 • Once a bonus for a successful Ram Impact has been granted and the team has placed the Bonus Card on the Tester weight stack, no weights under the Bonus Card may be removed. Weights added after the latest Bonus Card may be removed. • After the Presentation time ends, the Weight Placement Appraiser will note the weight that the Structure held.This is called the Official Weight Held, which includes the weights and the Pressure Board. Only the weights that are physically on the Pressure Board when Weight Placement ends are included in the Official Weight Held. • The Weight Placement Appraiser will also total the number of successfully survived Ram impacts. These are indicated by Weight Bonus Cards received by the team (See A.4.d&e). The number of Bonus Cards multiplied by 50 will equal the Total Bonus Weight (TBW). • The Weight Held Ratio (WHR) is the Official Weight Held in pounds plus the Total Bonus Weight in pounds divided by the Structure’s weight in grams (measured to the nearest tenth of a gram), rounded to two decimal places. Weight Held Ratio = (Official Weight Held in pounds + Total Bonus Weight in pounds) ÷ the Structure’s weight in grams Example: If the Official Weight Held is 195 pounds and the Total Bonus Weight is 200 pounds (4 survived Ram impacts) and the Structure’s weight is 52.3 grams, the Weight Held Ratio is 7.55 (WHR = (195 + 200) ÷ 52.3 = 7.55).

  34. A. Central Challenge – Section 5 5. The Ram: The Tournament Director will provide the Ram for use at the tournament. (See Section D.4 for a diagram of the Ram.)The Team does NOT bring, and cannot use, its own Ram at the tournament. For the purpose of this Challenge, a Ram Impact is the act of striking a marked corner of the Pressure Board with the Ram. Each Ram Impact will be delivered by a team member. The Ram has been designed to deliver a calibrated impact to the Pressure Board when operated as directed.When a Ram Impact is required, it will be performed in the following manner: a. The Ram starts in the Ram Box-- a taped area at least 3ft (90cm) from the Tester. b. After the Weight Placement Appraiser determines that the team has successfully placed 45 pounds or more on the Tester weight stack, the team will remove the Ram from the Ram Box and place it next to the Tester. c. While the Ram is outside of the Ram Box, Weight Placement stops. During this time, only team members operating the Ram may be inside the Safety Line – a line taped 10in (25 cm) from the edge of all sides of the Structure Tester on the floor of the Presentation Site. The Safety Line around the Structure Tester is viewed as an imaginary plane that extends vertically from the floor to the ceiling. d. The team will place the Ram so that while at rest, its impacting face squarely contacts (touches) a marked corner (team choice) of the Pressure Board.

  35. Questions for Appraiser Training Challenge E: Twist-O-Rama 10. The Weight Placement Appraiser has announced to the team that a Ram Impact is required. While one team member is moving the Ram from the Ram Box to the Structure Tester, another team member grabs another weight and is moving toward the weight stack. What should the Weight Placement Appraiser do? 11. The Weight Placement Appraiser has announced to the team that a Ram Impact is required. The team then moves the Ram from the Ram Box and places it next to the Pressure Board. The Weight Placement Appraiser notices that the team is using a different corner than previous impacts. What should the Weight Placement Appraiser do?

  36. Questions for Appraiser Training Challenge E: Twist-O-Rama 10. As long as the team member with the weight remains beyond the Safety Line, the Weight Placement Appraiser should say nothing. However, if the team member crosses the line, the Weight Placement Appraiser must remind the team of the safety rules and stop the action until the team member backs away from the Safety Line.

  37. Questions for Appraiser Training Challenge E: Twist-O-Rama 11. The Challenge (A.5.h.i) states the Weight Placement Appraiser is to determine that Ram procedures were followed before granting a Bonus. The Challenge does not say that it is up to the Weight Placement Appraiser to coach the team if they are not following the Ram procedures. Therefore, the Weight Placement Appraiser should do nothing to stop the team. After the Ram Impact, the Weight Placement Appraiser should tell the team why they are not granted a Bonus, and have them retry the Ram Impact.

  38. A. Central Challenge – Section 5 • The team may not alternate corners for subsequent impacts, and must use the same corner face for each impact. Each of the eight corners of the Crusher Board will have a unique identification label to assist the Team in meeting this requirement. • The team will then pull back the Ram until it rests against the Ram stop. The team will then release the Ram. • The Ram may not be touched by anything or anyone after it is released, until it stops moving. • When the Weight Placement Appraiser determines that the Ram has completed an appropriate impact, that four (4) seconds have elapsed, and that none of the requirements listed in D.7 for Weight Placement to end are met, then a 50 pound Bonus will be granted. The Weight Placement Appraiser will inform the team of the Bonus grant, and give a Bonus Card to the team for placement by a team member on the weight stack. The decision of the Weight Placement Appraiser is final. • If the Weight Placement Appraiser determines that Ram procedures were not followed by the team, the 50 pound Bonus for the impact will not be granted, and the Team will have to perform another RAM impact immediately before additional weight may be placed. The decision of the Weight Placement Appraiser is final. Possible procedural issues include:

  39. Questions for Appraiser Training Challenge E: Twist-O-Rama 12. After a successful Ram Impact, the Weight Placement Appraiser hands a team member a Bonus Card, which the team member dutifully places on top of the weight stack. A different team member begins to place a new weight. The Weight Placement Appraiser notices that the Ram has not been moved back into the Ram Box. What should the Weight Placement Appraiser do?

  40. Questions for Appraiser Training Challenge E: Twist-O-Rama 12. The Weight Placement Appraiser should stop weight placement until the Ram has been fully moved back into the Ram Box. This is considered a safety issue, not a procedural issue. The Weight Placement Appraiser should always stop the action when he/she sees a potential safety issue.

  41. A. Central Challenge – Section 5 • Ram not aligned squarely against the Pressure Board corner. • Ram was not pulled all of the way back to the Ram stop. • Ram did not impact the same corner as a previous impact. • Ram is touched by anything or anybody after released before it stops moving. j. After each successfully completed Ram Impact, the Ram will be removed by a team member to the Ram Box until the next increment of 45 pounds or more is successfully placed on the Structure Tester.

  42. A. Central Challenge – Section 6 • Structure Scoring: It is the intent of the Challenge that the team will create a Structure according to the specifications in A.2 and A.3, and will test the Structure at the tournament. • If the Structure does not meet the specifications in A.2 and A.3, and if the team is unable to bring the Structure into compliance with the specifications, the Official Weight Held will be zero. However, the team may still present its solution and earn points for other Challenge requirements. • Any team that does not make a “good faith” attempt to present a Structure for testing may earn points for other Challenge requirements, but they may not advance to the next level of tournament competition. The Appraisers will make this determination. Their decision is final. • The team will earn points for the Structure based on: • The Weight Held Ratio (See A.4.j). • Creative use of the Structural Materials: The team will be asked to describe their Structure and explain why they chose the various materials. The team’s design will be appraised on how creatively the multiple materials were included and used. • The production of a Bill of Materials (BOM) containing a list of all the materials used in building the Structure. Examples, and/or packaging of each material used must be presented with the BOM at Check-In. This BOM will receive points if present, no points if absent.

  43. A. Central Challenge – Section 7 • Story with Twist or Surprise, and Prop or Costume: • The team will create and present a Story that has an unexpected twist or surprising change.This twist should contain an element of surprise for the Appraisers. • The team will receive points for the creativity and surprise of the Story twist. • The team will receive points for how well the Story is integrated with Weight Placement and Ram Impact delivery. • The team will build a prop or costume made from only the same material types used in their Structure. • They must include only all of the same material types used in their Structure. • ii. They may only use the material types used in their Structure. No other materials may be used. • iii. Only one prop or costume must be built of the same material types as the Structure. All the other props and costumes used in the team’s Presentation may be built of any materials desired. • The team will receive points if the material types used to build the one prop or costume are the same material types used to build the Structure, and for the creativity and workmanship of the one prop or costume.

  44. A. Central Challenge – Section 7

  45. B. Team Choice Elements B. In addition to the above requirements, the team must present TWO creations called “Team Choice Elements” that show off their interests, skills, areas of strength, and talents. The team may create anything they wish for Team Choice Elements including props, music, technical gadgets, costumes, physical actions etc. 1. The team must present both Team Choice Elements as part of the eight-minute Presentation and each Team Choice Element should have a meaningful connection to the team’s Central Challenge solution. Each Team Choice Element must be described briefly on the Tournament Data Form found at the end of this Challenge.

  46. B. Team Choice Elements 2. A Team Choice Element may not be a specific item that is required in the Central Challenge that is already being evaluated. A Team Choice Element MAY be a single unique PART of a required item, as long as it can be evaluated as a stand-alone item. Both Team Choice Elements may be presented at the same time ONLY IF both can be easily identified and scored separately. Examples of these can be found in Rules of the Road. 3. Each Team Choice Element will be evaluated in three ways: for the Creativity and Originality of the Team Choice Element, and for the Quality, Workmanship, or Effort that is evident and Integration into the Presentation. Evaluation of Team Choice Elements is subjective.

  47. C. Reward Points – Scoring Category 1 The Structure’s Weight Held Ratio Up to 140 points • In each competition Level, the Structure with the highest Weight Held Ratio (including the Bonus Weight) will receive 140 points. • The score for all other teams in that Level will be based on the percentage of their structure’s Weight Held Ratio compared to the highest Weight Held Ratio in that level. Team’s score = (WHR ÷ highest WHR in Level) X 140 • This score added to the scores the team earns for the items listed below will equal the total Raw Score

  48. E. Reward Points –Scoring Category 2, 3, and 4 • How creatively the multiple materials were included and used in the Structure Up to 20 points from A.6.c.ii • Structure Bill of Materials and Material Samples 0 or 10 from A.6.c.iii • Story with Twist and Prop/Costume Up to 70 points • Creativity and surprise of Story twist Up to 20 points from A.7.a.i • How well the Story is integrated with Weight Placement and Ram Impact Delivery Up to10 points from A.7.a.ii • Material types used to build the one prop or costume are the same material types used to build the Structure 0 or 10 points from A.7.c.iv • Creativity of prop or costume Up to 15 points from A.7.b.iv • Workmanship of prop or costume Up to 15 points from A.7.b.iv

  49. E. Reward Points – Team Choice Elements Team Choice Element 1 up to 30 points from B a. Creativity and Originality up to 10 points from B.3 b. Quality, Workmanship, or Effort that is Evident Up to 10 points from B.3 c. Integration into the Presentation Up to 10 from B.3 Team Choice Element 2 up to 30 points from B a. Creativity and Originality up to 10 points from B.3 b. Quality, Workmanship, or Effort that is Evident Up to 10 points from B.3 c. Integration into the Presentation Up to 10 from B.3

  50. E. Reward Points – Team Challenge Scoring Central Challenge Scoring at a Glance • Instant Challenge = 25% • Team Choice Elements 60 points = 15% • Central Challenge 240 points = 60% • Story w/Twist & Prop/Costume = 30% of the 240 Central Challenge points • Structure Bill of Materials = 4% of the 240 Central Challenge points • Creativity/Workmanship of Structure = 8% of the 240 Central Challenge points • Structure Weight Held Ratio = 58% of the 240 Central Challenge
