The WPI is a dynamic way to determine the value of wins and losses according to the varying strength of schedule for each team. WPI software determines the value of the cumulative wins and losses that each team has against other teams, including out-of-state community colleges. Results against junior varsity, club and alumni teams are excluded from earning points and being factored into a college's score.
A win against a team with a winning record earns more value than a win against a team with a losing record. Conversely, a loss to a team with a winning record is less detrimental than a loss to a losing team. At the time of each report, each team's current winning percentage is assigned a number value from among 16 sectors (separated by 6.25 percent increments). The value of a win or loss can change after each game due to potential "sector" changes to their opponent's sector. In other words, teams move up and down depending each game's outcome, which is why we use the word dynamic to explain the value of a win and or loss.
A team's cumulative rating points are then divided by the number of games played. Rankings are then sorted by highest to lowest ratings.
