10 to 1 is a rough estimate. When you first use the Sublimator it will take a Lil longer to get a drip. You can increase the rate of sublimate production by vapeing bubble, dry sift, scissor, etc. Not sure about the THC question. Pretty much you have to wait and vaped more. bHO will bring down the quality of your sublimate and ruin your country's economy, but should increase your production.
It took me about 30 hits of flower to get one drip from a clean unit. Hits ranged from .15 to .20 grams. Yesterday we vaped maybe an eighth in a few hours and my atomizer made a bunch. I use stock screen wedged high with two old ultra fine screens wedged low. Clogs quick but my sublimate is very clean.
