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

Not contribution count. A merged pull request into a repository you do not own is worth twelve points because somebody else had to press merge; a commit is worth one and is capped at ten a day. Reviews you gave count for eight, 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 the whole thing resets on Monday.
