Since how hard you draw on the whip is very important to the actual vaping temp, it's really up to you to determine the vapor range. How the knob is installed on the unit can also make a big difference. Your particular unit could switch on at 7-8 o'clock, or at 6 or 10. You can pull the knob off and position it so it turns on at 12 or 1, and some have come of the box like that. As for draw speed, if you hit it hard, 3 o'clock could be a good setting (if it turns on at the usual 7-8). If you hit it nice and easy, 12 o'clock may be a better setting. You need to find the low and high end settings for your particular unit, and decide where the medium setting is that suits you and your draw speed.
Here's a study with vaping temps and what you get with rising temps. The toxins listed probably affect the type of high more than your health, since the levels are low. Basically, the higher you go in temp, the more the high resembles smoking, and the more smoke byproducts (toxins) you get.
There's a reason good quality vapes like the DBV, SSV, etc. aren't digital, while cheap ($50-70 range) whip vapes on eBay are pretty much all digital. Cheap digital isn't accurate, and it isn't reliable. Even the digital Volcano only has a two yr. warranty, vs. 3 for the analog Classic. If I want the best assurance that my vape will still be working, post warranty period, I'm buying analog. Our expensive, front loading washing machine quit working the other day. It died because of the digital circuitry. If it had been a simpler, analog machine, we wouldn't have a pile of dirty clothes today. :/
