Over the falls, in a barrel
Yep, I think that pre-heat up time is the biggest factor but only if draw speed is taken as constant. If you're dead set on pulling harder you have to wait for the heat to build to the point where that will work.After trying so many techniques and toying around with this thing since February, I'm really coming to learn that original heat up time will make the difference in how this thing works. And, that heat up time will vary from various batteries, temperature of the device from a cold start (i.e. if it's left in a hot car warm up will be short), and the switch and or cart degrading. So don't mind the 20 or 30 second rule as that will change based on circumstances. Rather, go at it when you feel a good amount of warmth around the intake holes on the outside. If it's slightly warm, you'll get flavor on the first few hits with not a lot of vapor. If it's warm-hot, you will get bigger clouds right off the bat. So it's up to you on how to use it. But the longer the warm up, the easier it tends to be to use... especially for beginners.
The tip about watching for heat rather than waiting a pre-set amount of time is good, but I find that holding the cart itself with the MP off while heating up, and waiting for that to get warm, will get you going if you draw at the right speed. Of course it's important to hold it from a cold start; heating first and then touching the cart to check could give you a nasty surprise...
Waiting for the heat to migrate down to the intake holes will take longer but allow you to get going with harder draws sooner.
