what exactly do you mean? does it scale linearly until it hits the target value at act part x? so if you put 12 then it scales until it hits the value in act part 12? if that is the case, where in the game is act part 12?
also hardcoreNPC is the modfier for tacitician mode as far as I know, it doesn't have anything in act part in vanilla so I just left it empty and modified the armor boost and magic armor boost values, as well as vitality, rest I left untouched
