Olympics, WC, USAs. The worst part of all these events are the rounds. The second worst thing is country entry limits, but that’s a rant for another day.
HS invitationals and even the HS national championships is the best format for a meet.

I’ll die on this hill. Heats are the #1 thing hurting the sport’s popularity with fans.
