I do, I just think you have never really shown the chess rating system to be transferable to analysis of individual players. Though if you really must keep up the chess comparison it's like comparing the win rate of opening variations while ignoring that one may have been played thousands fewer times than the other
You are right, I did suggest categories for a player's activity as a companion to the ratings.
There are other ways to show this information, but for me the information has always been on how the ratings travel and how they are interlinked with each other, and not just the end point of a rating with the variation of travel given as well.
It is messy, but it contains information that is not usually shown.
Just can't do it both ways.
