The Curve's formula is ''y'' = 2''x''-(''x''/10)^2, where ''y'' is the "effective skill" and ''x'' is the raw skill number. For example, at 50 raw skill in mining, one can get 75 max. ql of ore, since their effective skill is 2*50-(50/10)^2, which equals 75 effective skill. The reverse formula for this equation is -10*((100-''y'')^(1/2)-10) = ''x''.
