Suggested Idea for Performance Grading

Mochy’s 4.0 club criteria has set a new standard for excellence which I believe is very beneficial for the future of the game we love (well most of us). I wondered whether the idea could be extended to provide a series of performance grades similar to the international chess grades. Here is my tentative proposal for correlating longterm fair PRrates with the following suggested grades:
Candidate Master (CM): average pr rate of 6.0 or better from 10 consecutive live tournament matches of 7 points or over under clocked conditions.
Master (M): average pr rate of 5.0 or better from 10 consecutive live tournament matches of 7 points or over under clocked conditions.
International Master (IM): average pr rate of 4.0 or better from 10 consecutive live tournament matches of 7 points or over under clocked conditions. (Equivalent to the criteria for membership of the Mochy 4.0 club)
Grand Master (GM): average pr rate of 3.5 or better from 20 consecutive live tournament matches of 7 points or over under clocked conditions.
Super Grand Master (SGM): average pr rate of 3.0 or better from 30 consecutive live tournament matches of 7 points or over under clocked conditions.
Match winrate criteria could also be used by normalising the win rate to what would be expected against a Master (pr rate of 5) and then computing equivalent prperformance. However, to provide the same reliability as the true prlevel criteria, a much bigger sample size would be required.
I would be very interested to know others opinions on this approach and on the prlevels tentatively suggested.
