Tied in rank player received 15 extra points plus the difference in Games won by.
Higher ranked player receives 15 extra points for beating a lower ranked player plus points for the difference in Games of Sets.
The loser of any match receives points equaling the number of Games won in all Sets, but never more than 10 points.
The winner of a match that is played against a player more than 10 positions away will receive the points as if the players are only 10 places apart.
The point system has been designed to encourage activity by awarding points to both the winner and the loser. The number of points received by either player for a match is rounded up to the nearest whole number. As an example, suppose Ted, ranked 9, challenges and defeats Bill, ranked 5, with a score of 6-3, 1-6, 6-4 during week 7 of the ladder. Ted would receive 2 point for challenging, 15 points for the upset, and (5 x 4) / 2 = 10 bonus points for Games won, for a total of 27 points. Bill would receive 1 point for any Games won up to the maximum of 10 points for his loss.
If there was no recorded Challenge then the player entering the match gets the challenge credit.
