In my opinion the best format fo a Jai Alai performance for fans and players was started by Berenson many many years ago.
12 games
3 singles (4,7 and 10 games)
10 and 12 game were championship games.
3 groups of players (early, middle and late)
This format worked in all frontons for a long long time.
Most of the time the K.I.S.S. method works much better.
