I'm undecided on how to treat 'running the exact same torture sim (say as a flipbook of instructions)' but I'm leaning towards it being increasingly morally worse the more time one runs the simulation because of one thing that sticks out to me: that if you complete the torture sim then ask the person in the sim if they think they're a person, if they think it's okay to torture them because they're a copy, etc they're going to have every reason/argument a human in meatspace has against torture being done to them.
