I'm gearing up my 8 crafts to be 4 star.

Now I'm wondering what sweet spot it is for Craftsmanship and Control.

Is there a use to having Craftsmanship of 452 to ??? whatever max there is?
Is there a use to having Control of 408 to ??? whatever max there is?

It'd allow me to better plan my offhand melds, skipping Control if there's no point, and adding enough craftsmanship or slightly more to hit whatever the sweet spot is~

And to have 398 CP with HQ bouillabaisse of course.
