Spreadsheet results conclude that the time elapsed in sleepmode has no bearing on the 2 click issue.
Tested on 1 ohm coil at 30w - PANASONIC NCR18650PF
Tested at 10, 20, 30, 40 sec after entring sleepmode.
Allso tested with how many times i vape after exiting sleepmode.
Moore often i would get 2 clicks if i vaped 3 times after exiting sleepmode, while mostly getting 1 click after vaping 2 times exiting sleep mode.
Try one long vape and let it sleep. I'm not sure but I am thinking it has to do wit the amount of time the button was pressed last ....not sure. Ive been trying it but seem to be getting close.
