I have to tell you respectfully I've been mixing this base for over 2 years, I've never shared this method exactly for the reason of what you just did, which is criticize me for communicating the way I communicate.
I use PG as an antifreeze in my water lines in my camper in the winter. To me, PG is antifreeze. It is a food safe anti-freeze. The bottles are of it are also labeled as such.
There are people that cannot vape because of PG. I've been asked by more than 4 people to share this information. I did.
