Classement Vuillemot International

The computation should be :

The ranking is updated after every contest : a numerical level is computed for every pilot based upon his performances in FAI-approved soaring contests, each contest being quoted after its value.

Contest's quotation, pilot's performance and final level all are figured between 0 and 1000 points.

A pilot's level of 1000 points would be that of one pilot 3 times consecutively world champion.

The ratio between points level of two pilots should be statistically the mean of ratios of points (in final results) these two pilots would obtain in same competitions.

Formula :

* level = points in previous year international ranking ; the 3 best pilots are the 3 pilots in first ten of final results (or in first half if there are less than 20 pilots) who have the better level in the previous year international ranking

For instance, in a European Championship in 1996 with 25 entries, if
the 1995 level of first ten are :

950, 0, 930, 880, 920, 910, 945, 850, 915, 660

the quotation will be :

(2100 + 980 + 945 + 930 ) / 5 = 991, limited to 990

For instance, in a European Championship quoted 990, if the winner has 5000 points and the following 4900 down to 2500, the winner's performance is 990, and the following's 970 down to 495

Best performances are added first, as many as necessary
are taken into account until sum of coefficients is equal to 1 (last coefficient
is diminished if necessary so that the sum is not superior to 1)

If there is not enough performances to get 1, one fictive performance
equal to the best, minus 100 points is added with the coefficient needed
to reach 1. This allows pilots with only 1 good result in the 6 years to
be ranked at a representative place, but their level equal to their performance
minus 40, 70 or 90 points wether it dates of 1, 3 or 5 years (the same
with 0, 2 or 4 years).

To be coherent, performances of a given pilot below his best minus
100 points are ignored.

Contest coefficient may be diminished if numer of pilots or numer of tasks is too low, but this rarely happens in international competitions.

After each result, the ranking can be updated ; the performances in current year may only improve the level (points) of a given pilot ; of course placing may vary in both ways.

At the end of the year the places, but also the level in points, can be compared to the last year ranking. A countries ranking is finally established with the mean of 5 best pilots of each country.
