About cooking duration

Hi, when a cook cooks a Recipe with the duration 30 (30/10 -1 = 2) and it is Tick 1.

when is he finished? At the end of cooking of Tick 2 so that the dishes can be served in Tick 2 or At the end of cooking of Tick 3 so that the dishes can be served in Tick 3?

Hi, in your example, this cook started cooking in Tick 1, then he finished cooking in Tick 3, if there is an available waitstaff who can serve then this cooked meal is also served in Tick 3.
