Players gain points for singles matches they win and lose points for matches they lose. The mean and standard deviation is recalculated according to the rating of the opponent or the skill difference between the two competitors in each match. It is possible to gain/lose 0 points. The rating is recalculated after each tournament or when matches are submitted to Ratings Central for processing.
