It’s updated and more accurate than ever! We have pulled down a list of players with both chess.com and lichess.org ratings, subset them to only ratings with RD values < 150, and created formulas to convert the ratings. An RD value < 150 means the player is fairly active in that rating category. Each column compares between 55 and 130 players! Thanks Jesse for writing the code to pull down the ratings. There is an additional rating comparison on the chessgoals website showing that chess.com follows very closely to USCF ratings.
