I'm trying to figure out what the skill level should be at given levels for a specific skill use distribution. However based on the formulas shown on UESP http://www.uesp.net/wiki/Skyrim:Leveling it should be 544690.6 xp required to get destruction from 15-100, which is 39% error. Does anyone know where this formula and skill improv. modifier were found?
Skill Improve Mult * skill level1.95 + Skill Improve Offset
According to math, the skill improv. modifier for that formula should be 1.46 not 2 or 1.35.
