I guess I just don't agree with the benchmarks as being a good means of progression. I find they're all over the place, and substantially inconsistent in both difficulty and in quality. For reference, I've done all of the 2016 benchmarks up to 7A+, all but 1 of the 7B's (Ironarm), done 7 of 14 of the 7B+'s, 8 of 21 7C's, 5 of 9 7C+'s, and 1 of 3 8A's. For it being all a standard board and hold setup, that seems to me like a massive variance.
