In Fall and Winter Seasons (usually 15 weeks), divisions may have up to 8 teams. In the Summer Season (usually 12 weeks), divisions may have up to 6 teams. If more teams sign up for any division/night, then the division is split into squads called Blue/Red/White/etc. and play separate schedules.
In Team Leagues splits are normally done by blind draw; in Doubles League, splits are normally high/low brackets based on average rating of the teams. In all cases, divisions are considered equivalent for all rating, average and ranking purposes. However this may vary at the discretion of the Board of Directors.
Doubles leagues are rated (and re-rated) each week based on the team/division averages, in accordance with Rules & Regulation Addendum section 7.
MVPs are awarded in Mixed Doubles League for both male and female players.
