We don't have many F16 only events, I can only think of one per year.
I remember one of these F16 only events (Gulfport F16 invitiation 2 years ago), we had alot of F16's, but it was blowing like "stink" (25+ knots and gusting) on day 1, so all the uni's doubled up. Granted we had 3 less boats on the start for Saturday, but the racing was excellent. And Yes, the usual suspects still placed 1-2-3.
Racing was more exciting because most boats were "in" the race ... not capsized for being overpowered.
Day two was more manageable and we went back to uni config ... putting more boats to the line. Again the usual suspects finished 1-2-3.
No one complained, EVERYONE had a blast and we toasted over beers and excellent food (did I say this was at Gulfport ... the best [censored] hosted regatta or club event (next to SpringFever) in the Eastern USA!
