Craftsmanship vs. Magic Craftsmanship

[tymora]

I think that each recipe should clearly state if it is magical or standard. If main hand / off hand influences this, it should be easy enough to list on the window that pops up after selecting main hand / off hand.

It is usually easy enough to see which type a recipe is, in 2 synths. Sometimes it may take more, but you should be reasonably confident by the 5th.
Do once with craftsmanship focus.
Do once with m. craftsmanship focus.

Compare the following values:
Min Quality Gained, Max Quality Gained
Min Durability Loss, Max Durability Loss
Min Progress Gained, Max Progress Gained (doesn't work well if you are way above recipe rank since max is capped at 20, use quality instead).

In general, if you use the correct craftsmanship, both the min. and the max. values will increase.

Other more subjective basis will be the number of "booms" and instability occurrences.

Anyway, it is not too hard to determine which type, so whether this is displayed or not is not really of consequence.
I am more concerned with what is the magic number for each recipe to aim for.
