I've melded my 2-star gear to wind up with around 856 craftsmanship (after soup). I think 856is the point where:
Muscle Memory, 2 ING2 RS and 1 CS2 results finishing with exactly 1436 progress. I don't know which rotation I'm using. MaMa or other (I never really looked). But my progress steps are those. And I wind up with 12 touches (so on average 11 IQ stacks) and because I only need 2 progress steps under ING2, it allows for being fairly flexible with those ING2 stacks. If a good shows up with ING2 up, I use precise touch since I still have enough chances to land the 2 RS I need.

When I first made my MH/OH, I focused on control. After doing some back of the napkin math, I found that I'd see greater gains from the craftsmanship. Needing one less step for progress and an 80% at another IQ stack trumps the added control. That's true regardless of what rotation you are using.
