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.

Only the matches the source publishes appear; what is missing is listed. The source gives the day, not the hour: two matches on the same day are ordered by a reproducible rule, which is not necessarily the real order.
