Skill gain is also faster due to this curve.
The Curve's formula is y=2x-(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.
A Google search can show a graph of The Curve's formula [http://www.google.com/search?q=2x-%28x%2F10%29^2+from+0+to+100 as a graph].
