How to find out how much progress/quality per click?

[nekochen]

Is there a formula which you use to find out how much progress/quality you get from per click? Craftmanship/Control vs Difficulty?

[Progress]
I find it easier to divide the curve into 2 parts.

If you are 20+ levels above recipe,
Progress = Floor(Craftsmanship/3)
-> The relationship is actually linear with a very small gradient but for practical purposes, this formula works. (You'll be off by 1 in some cases)

If you are within 20 levels, it is a degree 2 polynomial with intercept set at roughly Craftsmanship/3.
You'll roughly lose 1/3 of the progress gain when comparing a -20 level recipe with a equal level recipe.

[Quality]
Quality = Floor(0.35*Control) + 38

[Star Items]
1 star = Roughly 0.6 of Progress Gained and 0.725 of Quality Gained for a regular recipe
2 star = No idea

*Formulas subject to change as I get more data (when I am bothered with writing it down)
