Okay so let me give you the real reason i want a more concrete rulling on this I.e. So many action equal this long or at such a number of posts your done is because Part of the risk and fun here is in the "oh crap dont wear off now!" moments and the "gotta get some more fast" elements of the game. However I wanted something that seems more fair then "Your surrounded by cops and now because I'm GM the serum wears off" something that let the players know I'm not activily trying to screw them just because the fight was going badly for me. Also as thier resistence builds the duration will be shorter for the same dosage. Trying to figure out how to govern that. Those are my questions.
