[D20 Legends Project] Ashiel's Crunchy but Approachable D20

[Klara Meison]

So I know I still have that question hanging and I don't usually ask a second one simultaneously, but do you know what (if any) numeric formula is behind Pathfinder's WBL and XP by level charts? I tried a polynom and an exponent, neither fits.

I am this close to concluding that Pathfinder has no actual math behind all those fancy tables, because I already exhausted all sensible theories for how it might work.
