I searched, but came up empty, so forgive me if this has been discussed

I’m curious how much xp is needed from 1^1 to 4^80. We could then deduce the number of 1*, 2*, etc needed to get the 5* maxed.

I would assume there’s a simple algorithm for xp increase per level (maybe different per tier).

Anyway, if there’s a topic, please post a link for me. If not, has anyone done (or want to do) the math?
