Sigh. Always someone who's looking for an argument. I "came up with this" through fact finding. If you think your ISO is isopropanol and H2O, with no traces of anything else you're deluded. There are traces of impurities, but like I VERY clearly said, the majority of the 9% is water. Didn't think anyone needed to listen to a long diatribe about how a higher water content introduces more pollutants via absorbtion.
The "fast rate" you are talking about is also incorrect. It's not the speed at which the alcohol dissolves the THC, it's how much alcohol comes in contact with the THC. Water molecules don't dissolve the THC, so when THC is in contact with water, that's less that's in contact with alcohol.
But hey, people are gonna hear all kinds of info, some of it correct, and some of it wrong, and stated simply to make a person feel superior. If you want to argue, have at it. My info is there, take it or leave it. You can argue with yourself all you like.
