This is the recommended choice for large divisions (16 teams or more), divisions where there is a large variation in team skill levels, or divisions where there are not enough games in the season for every team to play every other team.

Division standings are based on team ratings, with rating points either transferred from the loser of a game to the winner, or regularly recalculated based on all known results.

NOTE: If you use this schedule type, be sure not to select the "None" rating calculator.

The Rating Percentage Index is a simple system for rating teams based on their winning percentage, their opponents' winning percentage, and their opponents' opponents' winning percentage. It is commonly applied to NCAA basketball and baseball.

With the RPI system, ratings are re-calculated on a daily basis, taking into account the strength of each team's schedule.
