Past rankings

How I rebuild a month: every ranked or approved score I hold that was set before the first of the month, the best pp per map under the pp system live that day, weighted at 0.95 per place. Bonus pp is estimated from the score count, so the total drifts from what the profile showed. Where osu!track or my own sweep recorded the profile within the month before, that figure is the total instead.

Scores I have not collected yet are missing, so old months grow as the collection fills in. Restricted accounts are left out, and a player who moved to or from Switzerland only shows up in the months they were Swiss. Before June 2014 there is nothing to rebuild from (pp v1), so those dates are the ranking pages the web archive kept.
