In Fall and Winter Seasons (15 weeks long each), divisions may have up to 8 teams. In the Summer Season (12 weeks long), divisions may have up to 6 teams. If more teams sign up for any night, then the division is split into Blue/Red squads and play separate schedules.
In Team Leagues, Blue/Red are split by random lot and are considered equivalent for all rating, average and ranking purposes. In Mixed Doubles Leagues, Blue/Red are high/low brackets based on average rating of the high man and woman on the initial rosters.
Players who play only in Mixed Doubles are assigned a rating by the Ratings Committee at the end of each season. Otherwise, they receive the rating that they earn in the Team Leagues.
MVPs are awarded in Mixed Doubles League for both male and female players.
