Well, I think you might be underestimating this. Significantly.
Let's take a look at one of our National Champions classifiers:
He is currently at 98.xx%. Included are 3x Hundos (one of which is a match win), and 3 x 97s
Looking more closely, what were the other scores that were shot:
73
67
69
83
86
46 (followed by 100 on a reshoot)
73 (followed by 97 on a reshoot)
59 (followed by 100 on a reshoot)
100
41 (followed by 87 on a reshoot)
91
65
52
60 (following a zero)
92
96
46
57 (followed by 92 on reshoot)
36 (followed by 93 on reshoot)
94
58 (followed by 92 on reshoot)
So clearly, even the best of the best still have issues. The statement that the top shooters have little difference between their typical performance and the high hit factor is laughable. The HHF, in my opinion based on a sample size of 1, is unlikely to represent the typical performance of the pinnacle at our sport. I suspect if you went through the classifiers of the super squad, it would looked strikingly similar to the above.
