No, I dont and if you truly need to be pedantic a logarithmic curve makes even less sense. It’s a generally linear experience curve with each level being about 20-30% more than the previous, but the number get exceptionally large after a while. Level requirements aren’t scaled based on time required, they’re scaled on number of experience points required.
