That is an older ratings distribution table, but I wouldn't expect the numbers to change that much over just a few years. You can compare that one to the chess.com ratings distribution chart that is around here somewhere...
I have never played any tournaments so I don't have an "official" rating.
Here on chess.com I am in the 1400-1500 range currently in standard live chess which puts me in the 92.5% percentile, is this equivalent to anything in terms of UCSF? I am not looking for anything precise, just a general idea of what my rating here might mean, since I am just recently beginning to defeat players over 1500 rating here.
Thanks
