What you are saying is that many professionals are overrated or underrated (sometimes by as much as two stones). The same goes for amateur ranks too. So a rank estimate from a series of 7 stone games against a 4p will still have a error margin of one or perhaps two stones. I agree with that.

The reality is that the correlation between ranks and playing strengths is very low, and that knowing that player A is x-dan professional and player B is y-dan professional does not actually tell you very much about how likely player A is to win against player B.
