Is Elo rating accurate?
And, if you’re curious: the correlation of Elo and True Rating is 88.6%. This is far from definitive proof that Elo is better than win-loss. In fact, when I run this code multiple times, the win-loss is sometimes correlated better. The high correlation does however suggest that Elo is a decent method of rating players.
Why does Elo use 400?
The choice of 10 as the basis of the exponential and 400 as the denominator are just arbitrary: they were chosen by Elo so that a difference of 400 points corresponds to a winning probability of 90% for the stronger player. As a comparison, the rating of Magnus Carlsen (the World Champion) is around 2800.
How is Elo change calculated?
According to this algorithm, performance rating for an event is calculated in the following way:
- For each win, add your opponent’s rating plus 400,
- For each loss, add your opponent’s rating minus 400,
- And divide this sum by the number of played games.
Does Elo rating have a limit?
No, Elo ratings have no theoretical limit. If Alice scored 76% against Carlsen (rating 2853) consistently, she would stabilize at a rating of 3053*, and if Bob scored 76% against Alice, he would stabilize at a rating of 3253**, etc. There is no theoretical end to this sequence.
