If you were handling this (and if you were, we probably would have about 10 current cheer issues solved), how would you do it? Slow fix, quick fix? We'll start with score sheet seeing as change-of-venue isn't happening this year, but scoresheets have yet to be released..
Adopt the Varsity scoresheet as the universal standard for all divisions, including Worlds. (Most tried-and-true and vetted scoresheet at this point, not that I necessarily view it as intrinsically superior to the others.) <<As soon as feasible, this is replaced by the new universal scoresheet>>
Everyone starts in round 1. 1st round starts with at larges, partials, then paids, but random within those groups. Every other round is reverse order of rankings from previous rounds.
If division > 30 (prelims, semis, finals)
Top 20 (or top 1/2, whichever is larger) advance to semis
Top 10 advance to finals.
If division < 31 (prelims, finals)
Top 10 advance to finals
Address of gym plays absolutely no role whatsoever in determining any result. If you aren't one of the top 10 teams in the world, you don't get to place in the top 10.
Other changes:
In Field House: completely eliminate "VIP" area. Use that space for family/friends area which is standing-room-only and completely rotates out after every team. (You get to see YOUR team, but that is it.) Only coaches with a team IN THAT DIVISION or athletes from the performing team's gym (must be in uniform) can "cut" into that rotation. This is strictly enforced.
All scoresheets are released via PDF and google doc to everyone after every round. (comments redacted)
Awards held in another venue.
A massive social media venue is set up, with EXPERT & INTERESTING commentary provided live while each teams' performance is streamed live onto 3-4 massive screens. Let them have nearly free reign to say what they want, assuming it is family-friendly. Think of a cross between Monday Night Football, Mystery Science Theater 3000, & Perez Hilton.
