+# Leaderboards
+
+## Calculation
+
+The leaderboards are calculated for the previous range - so Daily leaderboards
+are calculated for the whole of the day before, Weeks from the week before,
+etc. - The only exception is all time, which is calculated from 00:00 on the
+current day.
+
+## Recalculation
+
+Leaderboard recalculation only affects the latest two leaderboards for any set,
+so just need to recalculate the last one and the current one, in that order.
+This can be done during the regular leaderboard calculation cronjob, so
+verified transactions will show up in the leaderboards the next day.
