Ranking Systems


20-Point Ladder System

Important: 2 out of 3 set scoring must be used for all matches for this system to work properly. A tiebreaker may be used in lieu of a third set at the discretion of the administrator. There are no ties in tennis, one player must achieve a winning score of 2 sets won. If a match is defaulted, enough games must be added to the score of the victor to achieve a 2 set win. If the match is not completed, do not record the score on tennisengine.com.

Scoring

  • If the winner is higher ranked he receives 20 points added to his previous point value.
  • If the winner is lower ranked, his previous point value is replaced by the value of his opponent's points - plus 20 points, thus "leap-frogging" his opponent.
  • The loser receives 1 point for each game that he wins.

This ladder design includes the most important feature of a traditional ladder, i.e. when you beat a player you move into a position above him. But unlike a traditional ladder, the loser receives a reward for his effort that is proportional to the performance of that effort. Conceivably, the loser may earn 19 points by losing a three set match in tiebreakers (7-6, 6-7, 7-6).

Ladder rankings are determined entirely by performance, while stimulating play in two important ways.

  1. A strong player can move to the top in one match but will surely be passed by others if he doesn't keep active. This prevents stagnation in the ladder.
  2. A losing effort gets rewarded for performance, but not enough to allow a player to maintain a high position simply by playing a lot of matches, often a problem in point accrual systems. Every losing effort also produces a higher-ranked winner. Winning is rewarded considerably more than just participating.

This ladder system gives a good credible ranking in a flexible and dynamic format. Anyone on the ladder can challenge anyone else, up or down, providing motivation for all players to participate. Anyone can rise as high in the rankings as performance justifies, yet no one can sit on their laurels.

The online league is updated every time a match is entered.

Please note: If a player is involved in multiple matches in a single calendar day, each match bonus is credited - but only as if each match was the only match that member played on that given day. In other words, "leap-frog" bonuses are not awarded to players who subsequently beat that player on the same day that he achieved a "leap-frog" bonus.
