Players are ranked per WADA rules.
15. Individual Player Rankings.
A. Players receive a rating based on singles win point (WP) percentage known as the Weighted Aggregate Rated Percentage (WARP).
1. The wins and losses are rated so that wins count more for the higher league (A3, B2, C1) and losses count more for the lower league (C3, B2, A1) for comparison.
2. The threshold for each WARP ranking is as follows:
AA >= 8.3
A >= 6.7
BB >= 5.0
B > 3.3
C < 3.3
B. All win-points and loss-points are totaled for a predetermined number of seasons which will be referred to as the Rolling Average Cycle (RAC).
C. A “RAC” should not include more than the last 6 seasons as a MAX.
D. A player must play 7 games (21 points) in the RAC to get a WARP.
1. Anyone who plays A league during the RAC may not be ranked any lower than B.
2. Anyone who plays B league as their highest level during the RAC may not be ranked any higher than A.
3. Anyone who plays C league as their highest level during the RAC may not be ranked any higher than BB.
WARP is calculated by first adding together the players' Singles Stats for the "last 6 seasons".
Then the following calculation is performed: (A wins*3)+(B wins*2)+(C wins)
divided by (A wins*3)+(B wins*2)+(C wins) + (C losses*3)+(B losses*2)+(A losses)
If the above calculation is an ERROR, then WARP = 0. Otherwise WARP = the above calculation * 10
