So Esq stands for Esquire?  I'll spare you the legal opinion jokes.  Before I answer you question, let me tell you of the post I just wrote.  I call it the distillation problem.  As I vape  (TC Mode) my etoh - h20 - pg - vg mix, clearly they are disappearing in order of boiling point.  So saying that I'm always at 100c isn't correct.  Yes, when there's water still in the mix, I sense a lower temperature.  However, there is a combined solution boiling point that I think I should hit to get a uniform vaporization (although I take it that you would argue against this).  And, ultimately why I want to know the boiling point is to make a judgement as to whether my TCR is set correctly.
