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).
