In Response To: Congrats RDR !! (Matt Cohn-Geier)

I believe that using ER as a method of comparing players is extremely overrated, in part due to disagreement about what "ER" means, in part due to inaccuracy in the formula itself, in part due to variation between matches...

And don't forget selective reporting.

OTOH, all methods have their weaknesses. I believe ER does the best at minimizing randomness.

I don't know if anyone has ever done a thorough study of variations in ELO ratings. I vaguely recall numbers like single S.D. of 80 rating points based upon bot online performance. And stable bots should have the LEAST variation, compared to unstable humans.
