This ranking system is based on the Association of Tennis Professionals Entry Ranking System. Players are ranked by the averages of the total scores of their best performances within a time period. This solves many problems with other systems; especially race systems that give preference to players who attend the most tournament events. This system ensures a more accurate calculation on the relative performances of players.

A player's rank is calculated using their best scores within a time period. Stronger players are not penalized for a "bad day", and weaker players are not rewarded for attending the most events. A player's weakest performances will be ignored in the calculations (provided that player attends enough tournaments to exceed the limit). The system will automatically weed out stale rankings and remove players who are no longer active.
