I think that with the relationships in Ohm's law, it really doesn't matter significantly from a theory POV what you manipulate. Is watts the final result that we are trying to stabilize? Maybe from a lektrik point of view, or maybe not. I think it is just another part of getting there. We are looking for small-particle nicotine vapor with a taste ultimately. I do know that in a 'evolved' (play on words kinda accidental really) manufactured board I would hope for more fault tolerance than I have personally seen on the Darwin.
