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.
