I would prefer comparing to power steering vs rack and pinionI fear Variable Voltage is like having a car with a gas pedal, but no steering wheel or gearshift. If you drive, it's better than not having it, but not much of a final solution. I rather like public transport.
Just like wine, there is a turning point for all liquids. Therefore the terminology/metaphor is more than suiting don't you think.I'm not sure artificial flavors dissolved in propylene glycol and glycerine sitting in polypropylene bottles resembles the aging of wine too much. There's some evaporation and some interactions of course.
I thought that since we fully control the juice composition, it's a better control point than voltage. Gummy, have you tried looking at what it takes to make the most high-persistence fog? Is it possible Raidy prefers a specific type? Or is condensation an objective across the board indicator?
The first statement is only true if you control all the elements. many do not roll their own.
I believe I was able to offer the OP answers to his original questions
