low, mid, high counts are the prelisted values and experience of mine (and other users; see the posts below)

the formulas >>> if we assume that the rate gets doubled e.g. 5%, 10%, 20%; so some (simple) math brings us to "100% = (X%*low) + (2*X%*mid) + (4*X%*high)"

with low=2, mid=6, high=5 "X = 100 / (2 + 2*6 + 4*5), X = 100 / 34, X = 2,94...."
