Now that's clear that we are not taking the same kinds of hits. As I said I would, I started counting lately. For my typical "large" load which was last time I measured between 0.10g and 0.15g (I didn't have my precision scale with me lately, but I'm pretty regular in the way I prepare my bowls, putting a fine line of material in my hand to judge the quantity by sight)
Anyways, my first session lasted 32 hits with a stir after the 19th, my second session lasted 26 hits, and the last one lasted 36 hits. My ballpark estimate was not far and even a bit on the low side apparently. So it's perfectly normal that I get less bowls per charge with my usage pattern, but I'm not complaining mind you!
Now that we are sharing usage tips, I would like to react to how
@Bravesst stirs in his above video (fun vid by the way, I liked how you almost rolled your eyes after the second hit heh) and also to
@pandaphysics's post above where he mentions using a second screen to prevent material from falling:
I use the puck technique in all my vapes. It started as a necessity with my conduction vapes arsenal, as conduction ovens require constant contact to increase the surface area being heated and the efficiency, but against all odds it also proved beneficial in my convection vapes!
Try it once please, if you don't like it the only thing you'll have to do is stir it loose and get back to your old habit.
It's simple and nothing fancy: just tamp the load to make a flat puck, using your pinkie or any other flat round tool. Don't over-tamp but do it enough such that the puck surface is flat and you can put the stem upside down and the puck stays in place.
Now provided that you don't stir
@pandaphysics, the load should stay where it is for the entire session and not a single crumb should fall. You don't need no stinkin' second screen man!
Then 2/3 down the session, when you start feeling a hint of "roasting" taste, flip the pancake! This doesn't work all the time but when it does it's really faster and less messy than
@Bravesst's stir: take your stem and put the end very close to the palm of your hand (close enough but don't burn yourself!) then blow once relatively hard.
With proper technique the puck will fall in a single piece inside your palm. Carefully flip it over then put the tip of the stem around it and suck it back. Sometimes it will crumble but most often not. In all cases just suck everything back, and re-tamp gently.
With this method I get even browning instead of a color gradient (that you get if you don't stir at all) and I don't need to do it more than once per session. Once you cook the other side of the puck there's nothing left. I tried stirring like above at first but it was always a mess with bits falling etc. Worse it tended to mix the dark bits with the lightest bits. With the puck flip it's now fast and painless, the dark bits find themselves on the other side and only fresh ones get exposed, try it!
