A weekly rank, scored on work that took someone else’s approval.

Not contribution count. Lines you wrote, credited on a curve so one enormous drop cannot buy a week, plus a share of the lines you reviewed for other people — which is why the top of a table is often somebody who wrote very little code and read a great deal of it.

Every score is ranked against a real crowd — the percentile above says which one and how many people are in it — and it is recomputed every day. Leagues settle on Monday.
