As Drexel said the sheet pretty clearly states the stat caps are as best I could CALCULATE for the masses based on the tiny amount of data on stat caps out there. I would STRONGLY advise against taking those as law.

I'd be VERY interested in relic cap tests, as the tests I do have do indicate that's the right range for relic (actually 380 main stat cap) - but that's limited testing at best and only from a third party source.
