I think there are two grace sites pre-elevator, so maybe it's 3 in the outside world or something - don't know.

For Roundtable Hold, I was guessing it was number of grace sites as I skipped past one between the Smouldering Church and the one nearest the minor Erdtree in the area and when I returned and found it was when I unlocked the Hold. Unless it's based on runes collected or something, but that seems less likely.

Or there might be multiple conditions for unlocking it.
