Profile - Percentile Calculations are incorrect
In the Fantasy Profile - the percentile calculation is the calculation of the % of opponents that you have beat. If you are in a 12 team league, the number of opponents is 11. If you finished 2nd. one opponent finished ahead of you and ten finished behind you. Therefore you finished ahead of 90.9% (10/11) opponents. Yahoo currently calculates as finishing ahead of 83.4% (10/12) opponents.
