that is calculated on how much pawprints per board (on average)?There seems to be no limitations in number of panda shrines you'd have.
Even without buying the premium line, you get plenty of those golden pandas,
and eventually let you grade up all the reserves to shrines.
It is sure tiring but 1 panda shrine looks like available with a little more than 10k diamonds,
and so, anyone who wants FP producers and is willing to spend, may consider that.
If you get 5 panda shrines, you get 200 daily FP, which is pretty much.
