Tennis Ladder Ranking Systems |
Tennis ladders use a variety of systems to rank the position of the players. Some tennis ladders use a leap-frog system where the winner takes the position of the loser. Some systems use a complex algorithm to determine player positions. These algorithms can take into account win loss records, opponents, margin of victories etc.. To keep track of the players positions, points are awarded. Below are the tennis ladder ranking systems used here.
Ranking Systems:
Leap Frog: This is the most basic and simplest ranking system. When a lower ranked player beats a higher ranked player, the lower ranked player "leap frogs" over the higher ranked player. If the higher ranked player wins, nothing happens.
The 39 point system: This system is the based on the classic Leap Frog system, but awards points to the winner and loser. When you win a player/team, you take their position on the ladder. This system not only awards the winners, but it awards the losers as well. This encourages players to play matches to maintain their ladder ranking. The number 39 represents the maximum number of games that could be played in a match (7-6,6-7,7-6). Here is how it works:
1. If the winner is the higher ranked player/team they receives 39 points minus the number of games the loser won added to there current points.
2. If the winner is the lower ranked player/team, their previous point value is replaced by the value of his opponent's points plus an additional 39 points minus the number of games the loser won.
3. The losers always receives 1 point for each game that he wins.
Example 1:
Jane wins John 6-3, 6-2
Jane had 42 points, John had 56 points
Jane now has 56 + 39 - 5 = 90 points
John now has 56 + 5 = 61 points
Example 2:
Jane wins John 6-4, 6-4
Jane had 40 points, John had 32 points
Jane now has 40 + 39 - 8 = 71 points
John now has 32 + 8 = 40 points
Note: A best 2 out or 3 set match must be played (any score can be submitted in the 3rd set). For doubles matches, averages are used to determine a team's points.
The 17 Point System: This system works exactly like the 39 point system, but requires you to play a pro set, and awards 17 points minus the loser's games instead of 39 points minus the loser's games. A pro set is won by winning 8 games with a margin of 2 or more games with a tie-breaker played at 8-all. This system is great for when time is limited.
Example 1:
Jane wins John 8-6
Jane had 15 points, John had 34 points
Jane now has 34 + 17 - 6 = 45 points
John now has 34 + 6 = 40 points
Example 2:
Jane wins John 9-8
Jane had 23 points, John had 14 points
Jane now has 23 + 17 - 8 = 32 points
John now has 14 + 8 = 22 points
Win/Loss System: This system awards point by your win loss record. For example, if you have won 2 out of 4 of your matches, you would have 50.06 points. Where 50.06 represents 50% win/loss percentage and 50.06 represents the number of matches played. This system ensure that players who have played more matches, would have a better ranking then players with the same win loss record but with less matches played.
The True Rank System: This system is loosely based on Elo rating system which many believe to be the most accurate system for ranking player ability. The True Rank System awards points based on current points, margins of victory and opponents points. If enough matches are played, the best players will be at the top of your ladder. Any type of score can be used for the matches.
