How would one create leaderboard buckets with a limit of n players and the ability to get to a better leaderboard based on the rank at the end of the period?
Most modern games use leaderboard tiers and buckets, like supported for example by Unity Services leaderboards: https://docs.unity.com/ugs/en-us/manual/leaderboards/manual/leaderboards
I have seen some questions from 2015-2019 but nothing recent and relevant.
