Well Max, lets favour elevated vapor-to-air ratios then!
One image often comes to my mind quite spontaneously when i think of this problem while watching typical vaporist videos; i see large pieces of glass with huge amounts of air contained inside and can't but tell to myself that the vapor is already diluted before it's even created! For me this parameter combined to the rate of inhalation, not to mention lung capacity, can only make dosage more complicated...
So, perhaps linking ratio and dosage the way i do it is not suitable but i'm certainly willing to adjust this perception when the opportunity shows up! If you've followed my fantasy thread then it should have been obvious why including the vapor bag in the vaporization cycle is so important to me: minimize the amount of air required to fill a ballon, i mean better have a potent falf-full balloon than a balloon full of thin air.
Still being a future vaporist i can't argue much but my impression is that a bag should prove to be versatile enough for a former smoker like me who wants to discover vaping. A bag would probably happen to be easier on lung capacity too; my bet is for a beginer things are sufficiently complicated not to want to deal with multiple learning curves all at once. The vocabulary is important in any case so i'll try to pay closer attention!
