Soaring Pilots International Ranking
Classement Vuillemot International
Rule
version française
Objectives :
To represent as accurately as possible skill of soaring competitors as
proved by results in FAI official category 1 events of last six years,
To select "best" of all pilots in all classes at one time, to compare levels
of different pilots between each other,
To help promote soaring competition (as ATP does in tennis)
The computation should be :
- fair
- reasonably simple
- easy to understand by pilots, public and media
- quick to update after any contest
- so that it incitates pilots to give their best
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.
Contest's quotation :
Each contest is quoted depending upon its intrinseque value (official FAI
title) and upon levels of participants, within a predefined
interval :
1000 points for a world championship provided enough pilots entering have
already a sufficient level in the ranking
990 points for a continental championship in the same conditions
...
920 points for a junior continental championship without any known pilots
Formula :
-world championship : ( 2100 + levels* of 3 best pilots, with 900 minimum
) divided by 5 ; limits : 960 to 1000
-world championship (motorgliders) : ( 2100 + levels* of 3 best pilots,
with 800 minimum ) divided by 5 ; limits : 920 to 960
-continental championship : ( 2100 + levels* of 3 best pilots, with 850
minimum ) divided by 5 ; limits : 940 to 990
-continental championship (juniors) : ( 2100 + levels* of 3 best pilots,
with 800 minimum ) divided by 5 ; limits : 920 to 980
-continental championship (women) : ( 2100 + levels* of 3 best pilots,
with 800 minimum ) divided by 5 ; limits : 920 to 960
-continental championship (motorgliders) : ( 2100 + levels* of 3 best pilots,
with 800 minimum ) divided by 5 ; limits : 920 to 960
* 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
Performance :
In any competition each pilot is credited by a performance equal to the
contest quotation for the first-placed, and proportionnal
to final result points for every other competitor.
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
Computation of level :
The level of any competitor in year n ranking is the mean of best
performances in last six years, ponderated by a coefficient which is
: - 0.6 maximum for any contest in year n or n-1 (last world or continental
championship) - 0.3 maximum for any contest in year n-2 or n-3 (previous
world or continental championship) - 0.1 maximum for any contest in year
n-4 or n-5 (first world or continental championship in the period of 6
years)
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.
Ranking :
At the beginning of each year, results of year n-6 are suppressed, and
new coefficients computed for each contest.
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.
