I've just dropped back from premium to free membership and I'm noting that in my rating range (I swing between 1100-1300 depending on how much I concentrate while playing) the free players seem to be around around 100 rating points weaker in terms of play given the same chess.com rating.
I know Matt Jensen and Jesse Buss from Chessgoals have the comparison of ratings between OTB and the various online websites but I'd like to know whether there really is a "true" ratings difference between free and premium players. I do know that as a premium player you tend to play more premium players so that this could lead to a ratings divide between the two player pools.
I've never seen any actual data on that.
