Just been doing a little bit if testing! Lost my scales so I loaded up the solo stem nice packed on a medium grind which from when I had scales tells me this is around .2. I managed to get 7 tiny little VG bowls tiny tiny sprinkles, one day when I can work photos out I'll do it. Anyways each load connected to water managed at least two nice decent clouds and someone times one or two more smaller clouds until very well spent! Spotting after two would probably be preferable to most. Obviously not science just anecdotal evidence I have found on my search for slowing down consumption (I went through an O in 2 weeks and while I don't mind smoking a bit as far as cost is concerned, this is getting a bit out of budget!!) now to work out the self control on the ease of loading another bowl. Although if each bowl is 1/2-1/3 the size consumption should show at least a little as a by-product!
