Indeed, this is about digging the MFLB's from the bottom of the vape related rummage pile. I'll give you tip on the ABV... Once you got what you think you can get from the LB, suck the ABV up in a your 'M'. There is typically one good draw left that removes the vape from the lighter colored flecks. Much easier than making the box do it. That is assuming you want the dregs. I don't have a choice - that's where my meds are. Turns out a full trench is 2 VapCaps. I've been doing this for the last week and things are much more efficient this way. I only fill the trench half way to make stirring easier.
