Odds and real cost
Our calculation from the recipe's chance table: crafts per success = 1 ÷ success chance; per combo result = 1 ÷ (success × activation × combo craft). Parts that a recipe can make are expanded too, each crafted at your proficiency minus its own recipe level. Assumed: a failed combo craft still gives the normal item (the game only says a successful combo replaces it), and one proficiency level for every profession.
