From 66 matches played between 7 September 2016 and 3 November 2026, and from them alone. Every line below was written at computation time: nothing is recomputed to show this page.

How to read this

On the right: the change this match produced, then the value before → after. A line's arrival value is the next line's starting value, down to the starting rating given to every newcomer. A ±0.0 is a counted match that did not move the rating, a walkover for instance.
