CEVO has developed and released the CEVO Performance Index (CPI), a mathematical formula for calculating teams’ overall performance during the regular season. CPI is carefully constructed to take into consideration all the important factors for seeding teams in the fairest, most unbiased way possible.
CPI is calculated using six components:
1) Point Index
2) Win Percentage
3) Strength of Schedule
4) Margin of Victory (does not apply to DoD)
5) Opponents’ Strength of Schedule
6) Head-to-Head Modifier
Point Index is calculated based primarily on the number of wins. Forfeit wins grant teams partial points, as do overtime losses.
Win Percentage is a straightforward calculation of a team’s wins versus losses.
Strength of Schedule is determined by averaging the Win Percentage of each of a given team’s opponents, minus the match between that team and that opponent.
Margin of Victory adjusts the value of a given win depending on the difference between rounds won and rounds lost.
Opponents’ Strength of Schedule is determined by averaging the Strength of Schedule for each of a given team’s opponents.
Head-to-Head Modifier takes head-to-head match-ups into consideration by providing a small bonus for beating higher ranked teams and applying a small deduction for losing to lower ranked teams.
Throughout its development, CPI was constantly scrutinized for effectiveness and fairness. It was important to not unduly penalize teams for ending up with forfeit wins, to include strength of schedule into the equation, and also to consider head-to-head match-ups. Furthermore, it was necessary to deal with the existence of dead teams, unplayed matches, and forfeit losses. You can be assured that the CPI formula considers each of these critical aspects to truly produce the fairest seedings possible.
