Three Star Master Recipes (Difficulty)

[Kenji1134]

Been wondering, with 391 craftsmanship, the minimum to make 3 stars, do you really need 3 CS2's under Ing2 to finish?
445*(1-5/9)/2 = 98.888 progress per CS2 to 2 shot the remaining portion. So you really do need 3?

Edit... Just tried a 3 star cul recipe, with 392 craftsmanship under Ing2, CS2 gives 70 progress... Yeah, no way to 4 shot it.

The crafting simulators seem to model progress fairly will for 3 star recipes, if you set the item level to 53, and dont use any ingenuity buffs. That said, even with say 424 craftsmanship, using a +32 craftsmanship food, it says we'll still only get 76 progress...
Well, ingame, at 416 craftsmanship, I am getting 75 progress under ing2. If we assume its a linear relationship, then we get 0.208 progress/craftsmanship... (99-70)/0.208 = ~140... We would need to add 140 craftsmanship over the min value to craft the item to do it with 2 CS2's.

...Damn...
