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 33 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 33, he gets automatically ranked as
34th. 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).
