Send all of your kids. Every single one of them. Top band through 6th band. That'll put plenty of dough in the region's bank account, so you can hire all-star clinicians and buy gold-plated trophies for everyone.
Use that money to buy a red light and a red button for every single judge.
Every judge gets unlimited buzzes. Three red lights and the monitor cuts the kid off, performance is done, and scored based on what they played to that point.
I would've buzzed 2/3 of the kids yesterday before the end of their first etude.
