I don't think the live game should be changed at all unless it is the case of a PK being awarded that would change the outcome of a game.
I am entirely referring to reviews of the dives after play is complete. I do not wish to disrupt the flow of the game. I think if retroactive punishments were handed out more frequently the Oscar winning divers would be very selective about when they are going to do it, instead of just doing it all the time.
