Main Court and DUPR launch a full integration — players can now see their DUPR rating inside Main Court, run DUPR-rated Round Robins, and automatically sync match scores to DUPR.

You have eight players, two courts, and ninety minutes. Everyone wants real games against different people, nobody wants to stand around, and you do not want to play referee all afternoon. The format that solves all of that is the round robin, and it is the single most useful thing an organizer can learn to run.
