Hello,
I see on chess.com that they are creating your feature of analyzing one's game with the "average centipawn loss". They are far away from what you have done and they make you pay for it, so I try to improve your site with a suggestion.
It would be very interesting to know the correlation between OTB rating and "average centipawn loss", for instance 25 "a.c.l." in 100 games correspond to 2200 OTB.... I understand that it is not easy to make this correspondance, so it would have some kind of imprecision, but it would be still very interesting i think.
However, I think it would be easy for you to analyse all games of all GM and IM and draw the correspondance. Of course, it would tell the correspondence for long games, so in blitz games, a coefficient could be applied... but still, analyzing rapid and blitz GM and IM games, you could estimate broadly this coefficient (for bullet, not sure all this has importance of meaning, this kind of chess is just for fun i would say).
It would be of immediate use for a player who want to attain 2200: he knows his goal quantitatively in termes of accuracy of play and he knows at what REAL strength he is playing.
