and Rating Comparisons

It's updated and more accurate than ever! We have pulled down a list of players with both and 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.
