What impact has starting point for rating accuracy? I thought, we can add a constant to each player's rating and the accuracy will be still the same.


You and I both know that the starting point has no relevance on statistical accuracy. I am thinking Jorge is referring to comparing engines to humans, but I am not certain.

According to Graham, the reason for ELO reduction was not the accuracy, but too high ELO ratings comparing to other lists. So the goal is to have the most similiar ratings in different lists, isn't it?


In the CCRL, it was suggested that our ratings were too high, and a majority of the members agreed. The lowering was definitely not to improve statistical accuracy. As you know, the only way to do that is to reduce sources of error and increase the number of games.
