Quarter by quarter gap to expectation, in points

A bar is the gap that quarter; a grey stub means too few matches to judge; the dashed bar is the current quarter so far.

The expectation uses each player’s own rating before every match, from all their partnerships — so the gap is what this pairing adds or costs. Includes qualifying. How ELO works
