The DUALS PERCENTAGE INDEX (DPI)

Explanation
Wrestling is somewhat unique in collegiate athletics by the method in which team scores are determined in dual meets. They are based upon how individual wrestlers perform against one another. Specifically, it is the sum of points earned over a total of ten matches pitting wrestlers against one another at varying weight classes.

Under such a system, it is better overall to rank teams wrestler by wrestler, rather than simply using the final scores of matches. This is the underlying principle of the DPI. Here's how it works:

1) A database is created of each D1 team with the top 30 individual rankings of each weight class as provided by WrestlingReport.com

2) A computation is made on how each team fares against each other as if they are wrestling in a dual meet. For each weight class, whichever team's wrestler is ranked higher than the opponent, that team gets 3 points. If a wrestler isn't ranked in the top 30, he gets automatically ranked as 31st. Bonus points (to simulate major decisions, tech fall, and fall) are awarded if the individual rankings between pairs of wrestlers vary by more than 5, 10, and 13; respectively.

3) Naturally, one team defeats the other when the point sum for its ten wrestlers is greater than its opponent. One team gets a win and the other gets a loss. Of course, ties are also possible.

4) Each team's DPI is calculated by dividing the number of wins by (wins + losses).
