The cut off point for AAA has hovered
miraculously consistently between 86.3 - 86.9 for the last 10 years. This is just a hobby horse for a few usual suspects who simply will not get their head around the fact that averages and classes are based around AVERAGES and that making targets harder OR easier will not make one iota of difference in who ends up where.
If you shoot scores that are in the top whatever percentage you will still end up in THAT group and be awarded the SAME class.
If you like hard targets no problem, set mega hard shoots and watch your livelihood disappear, if you like to shoot mega hard shoots no problem just buy yourself a 410 and teach the rest of us a lesson.
