More like my question is: what is the difference between those two parameters to begin with, since both seemingly sound the same way - "affecting stuff globally"?
Unless it's literally "two multipliers", one (Percent) affecting EVERYTHING, another (Default) leaving OUT stuff like units and costs, which are decided by the other two Adapts.
So if I put both Percent and Default at x2 (leaving Units and Costs at x1), I'd get culture at x4 (x2(Percent) * x2(Default)), but units only at x2(Percent), since Units are still at x1.
Right?
