Not that I'm the guy who would be knowledgable about the mechanics of an 11-man UIL school making the move to 6-man UIL, but I certainly wouldn't be looking at it with an enrollment number of 97 UNLESS I was pretty well certain that my total enrollment would be staying under 100 for the forseeable future.
The worst position to be in would be having an enrollment bouncing on each side of that 100 number every two years.
If I were the administrator of such a school, I think I'd be doing computations (using each of the calculations UIL allows) for classes four or five years down the line and seeing if I stayed under the 99.9 number AND having those folks on the school board sign off on it BEFORE I picked up the phone and asked UIL to put my school in 6 man.
