I took a quick download of the video, dropped it into iMovie and played with the playback speed a bit to try and find the 'normal speed' sweet spot. It was a bit tricky as the original Vimeo video had a bit of a slow frame rate to begin with. I just approximated what looked like natural movement speed when he was moving his hands. Around 17% video speed seemed to be at least close to the sweet spot. That puts the total runtime shown at around 8 minutes.
Thanks very much, this makes more sense (at least to me). I noted some fiddling with the bleed valve (closest camera), I assume to adjust vapor production rate by changing airflow. He also seems to fumble with the switch on load four (about 5:10), it seems to have timed out?
Anyway, taking my stopwatch to the actual heating/vapor producing time (that is the time it's actually connected to the hose and has air drawn in) I make the total at 3:47. With 'lap times' of :46, 1:24, 2:07, 2:58, and 3:47. Respective 'hit times' 46, 38, 43, 41 and 49 seconds.
It seems like 8 to 10 seconds to vapor for each hit? That makes sense to me I think.
As has been said, there's an unknown number of seconds left in the battery but that's less than four minutes of vapor (including 'warm up' to vapor each time) at an average 'step 3' (170C). Hopefully there's a lot of reserve power left.
More clues. Thanks again. Come on Member testing!
