I don’t know if you can control the heat of the disposable pads as I’ve never seen one. I think I’m going to try using a damp face cloth as a buffer tonight. The pad I use has a soft cloth cover that is supposed to attract moisture out of the atmosphere in order to help thermal transfer, but you’d have to let it heat for far far longer than I can tolerate for it to become a significant amount of moisture.
My current feeling is that this heat thing really does work, but suspect that it would need to be cycled (eg. 4 days on, 3 days off) in order to distinguish between stretching and rebuilding. I just got over excited at immediate impressive gains, then nothing at all, and lost perspective since I was seeing daily gains, and came to expect instant gratification (a recurring human fault :o ). If I switched to measuring monthly, the data might show a very different picture…
