Quite agree Mike and Dave though the regions firstly should submit scores to the BFTA for starters.
Personally cant see a problem with the number in each grade, what i do suspect is those at the bottom think no chance of winning either requesting a drop in grade or creation of AAA.
Better to shoot in top grade and come no where than win a lower grade.
Rich that idea sounds plausable in general based on the top 40.
Or make each grade the best 25% which would alter twice a year.
