Oh I don't disagree that efficient extraction is important, I'm questioning how one can objectively measure that as a user without any scientific means of measuring. Subjectively, I find the flavor to be just as potent as from my SSV. I get a nice, strong effect, but poor vapor production. The weed comes out an almost homogenous dark brown on the highest heat setting. So now what, how do I objectively quantify that experience, ya know? From my experience it is efficient with material and energy consumption. For a friend with considerably lower toelrance, where one hit on one petal heat will send her to the moon, is this is even more efficient, for her?
