Is rating dependent on the opponent

[Uri Blass]

H0 is that rating is not dependent on the opponent and you can use one opponent to find CEGT 120/40 rating of players.

H1 is that the rating is dependent on the opponent.

My question is if you can reject H0 based on the data.

Here is the CEGT 120/40 rating list

Note that even with only 50 games performance of the opponents are usually close to their rating

I do not find many cases of difference of more than 100 elo between rating and performance and I can expect a small number of cases when it happen even only by luck assuming that performance of programs is independent on the opponent.
