Scoring formula

[Grow Pattern]

Here is what the FAI sporting code says for FAI. (For AMA it looks like it is not specified - maybe we need to update the rules book?)

(Pretty tricky English - advise you read it a few times before drawing a conclusion or two)

5.1.9. Classification

Each competitor will have four preliminary flights, with the best three counting to determine the team

placing. All scores, preliminary, semi-final and final, will be normalised to 1000 points as described

below. The top one third, but not more than 30 competitors, will then have two additional semi-final

flights flying the known finals schedule. The total of the best three preliminary flights (normalised

again to 1000 points) will count as one score along with the two semi-finals scores to provide three

scores, the best two to count for semi-finals classification. The top ten competitors of the semi-finals

will then have four additional flights to determine the individual winner. Two final flights will be the

current known finals schedule and two will be unknown schedules (two different schedules) (see

Annex F) flown one time each. The known and unknown schedules should be flown in alternating

sequence. The best score from the known schedule will be combined with the best score from the

unknown schedules for final classification. In the case of a tie the semi-final score will be used to

decide the higher classification.

Scores for all rounds, preliminary, semi-finals and finals, will be computed using the Tarasov-Bauer-

Long (TBL) statistical averaging scoring system. Only computer tabulation systems containing the

TBL algorithm and judge analysis programs and approved by the CIAM Bureau can be used at

World and Continental Championships. All scores for each round, preliminary, semi-final and finals,

will then be normalised as follows. When all competitors have flown in front of a particular group of

judges (i.e. a round) the highest score shall be awarded 1000 points. The remaining scores for that

group of judges are then normalised to a percentage of the 1000 points in the ratio of actual score

over winner's score.

 Note 1: Final and semi-final flights to determine the individual winner are only required for World and

Continental Championships. For smaller contests the total of the three best preliminary flights may

be used to determine the individual winner and team placing.

Note 2: The TBL system can only be applied for events with at least 10 competitors and 5 judges.

For those smaller events that are not scored with the TBL system, the high and low scores for each

manoeuvre will be discarded if four or more judges are used.
