Suggestions for the Caber:
Normally, there should be three rounds of competition for the caber. But if after three complete rounds, the caber has not been turned by any athlete, a slightly smaller caber may be used for one more round, or the caber may be cut. The caber shall be cut from the large end and the amount is to be determined by the judge. This process can be completed after each additional round until the caber has been turned (maximum of 3 additional rounds).
When a qualifying caber is used then any turn qualifies the athlete for the next caber, where three rounds are conducted. The marks of the qualifying caber are not considered except 1) to break a tie after three rounds of the main caber are considered, and 2) the angle of the unturned qualifying caber are used to determine the placing of the unqualified athletes.
If the caber breaks during the competition, and another caber of suitable size and weight is substituted; then all three rounds of the competition are conducted with the new caber, and all rounds with the broken caber are not considered in the placing, except all completed rounds with the broken caber are used in breaking ties after all three completed rounds with the new caber have been considered.
In the event of a tie, the next best attempt(s) shall be used to determine the placing. The order of placing shall be determined by the nearest to 12:00 toss made by the athlete, followed by the unturned tosses closest to 90-degrees. After considering all three completed rounds of the main caber, the best of all completed rounds with a previously broken caber is considered, followed by the second best round of the broken caber (if there were two), followed by the qualifying caber(if completed). Ties for places other than first not broken by the next best attempt(s) shall remain a tie.
If a tie for first place still exists, successive additional attempts are made to break the tie, subject to the restriction that no athlete shall take more than six total attempts, including qualifying and both complete or incomplete broken caber rounds. (This means that if one of the tied athletes has already taken three attempts on a broken caber plus three attempts on the replacement caber, or one qualifying caber plus two attempts on a broken caber plus three replacement caber attempts, there are no tiebreaking rounds.)
Caber recommendations: It is beneficial to have a wide range of lengths, weights, and center of gravities of cabers on hand to choose from. The choosing of right caber is important. You want to avoid the situation in which almost everybody easily gets multiple 12:00 tosses, but you also want at least one person get a turn. The judge should heed honest input from the athletes as to which cabers they think they can turn, and the judge shall make the final decision of which caber to use. Too often there is not enough caber selection.
Caber construction: the small (tapered) end should be rounded in a semicircle; the large (flared) end shall be cut exactly 90 degrees with no rounded edges. One back judge and one side judge should be used. The side judge may use the assistance of a protractor, and the back judge may hold a clockface, to assist in determining angles and times.
Determination of places and ties: Here's my recommendation for a tiebreaking procedure: Places are determined by the best of the athlete's legal attempts. If two or more athletes have equal best throws, the places are determined by next best attempt(s). Ties for places other than first not resolved by the next best attempt(s) remain as a tie. Ties for first place (that is, in the case that all three throws of the athletes are equal distance) are resolved by taking one additional attempt. Extra additional attempts are successively taken, if necessary, up to three additional (six total) attempts. After all athletes have taken six total attempts, the tie will stand.
Extra attempts:
After normal competition is completed, the winner may be given up to three additional attempts to set new games, national, or world records. It is the athlete's discretion to use all, some, or none of these extra record attempts. Any tiebreaking attempts count against the number of extra record attempts, so that the total number of attempts should not exceed six (applies to all events except sheaf and weight toss for height).
