Kent, If the math that you refer to in this post is the only factor in the vapor production and therefore the nicotine absorption and throat feel then why do I experience more vapor, TH and flavor on my 901 mod with a 5.2 ohm atty than I do on my 510 mod with a 3.2 ohm atty using the same batteries and juice? There must be something more to it. The performance of my HV901 set up is nothing at all like a 510 at 3.7 volts. not even close.
Well, I could go into all the subjective reasons why things don't align with the math for many people, but here's a few examples of the math:

Wattage is what lights up the atty and the atomizer, atomizes

There might be a factor of how over or under heating might affect atomization but in every experience I've had with the combinations of voltage and ohms, it's been consistent with the math and there is a reason why LR attys are created and why HV attys must be used at higher voltages. An LR atty at 3.7V will out produce a high HV atty at 5V. As far as throat hit, that aspect is part subjective because it's your throat. I won't argue that point.
And the main thing is that if you're happy with your setup, then no amount of math matters. I don't know the tech on HV ejuice - you'd have to go to Drew at Nhaler for an explanation of that - I always thought it was just more flavor added but I really don't know, but getting close to the same wattage (via different ohmed attys) at 3.7v and 5v the ejuice tastes the same to me and the vapor is almost identical.
So for attempting to give objective advice to someone who is wondering what the factors are, I'm much more comfortable giving them the facts of the Volts, Ohms and Wattage than I would be saying 'my set up is the best'. Everyone experienced vaper thinks that or they would change. But that isn't of much help to someone who isn't getting vapor
