We had five people - so I decided to have a true doublette start and I'd wait on the sidelines until another player(s) showed to create a 2nd game.
A half hour later, Mark shows up - and I just felt it'd be best to jump into the existing game as a triplette.
So, while the theory of running as many games as we can sounds nice - the reality is that we only have 1 hour - and not everyone shows up at one time. That said, people would be waiting around not playing until other players showed up. That will only cause frustration and less people showing up.
So... my original formula works (unless there's enough folks at the beginning of the start time) of everyone playing as they show up.
Enough of that. Now on to today's game(s). The doublette began with Pat/Tim vs. Aaron/Mike then they were joined by Mark; Hitesh; and me.
