Everyone posts their PG/VG ratios in values such as 80/20, 70/30, etc
The sum of the two values is always 100%. What are these values supposed to represent, is it the percentage of PG and VG compared to the volume of the total mix or is it the percentage of the PG/VG content compared to the total volume of PG and VG in the mix? The later could be misleading on TH (PG volume) and thickness (VG volume). Most of the flavor ingredients I use in my mixes are not PG or VG based. If I am adding 25% flavors, that could have a large effect on the published PG/VG values. The best way to show the effects is to provide an exaggerated example:
I want to mix 100 mls of juice. My goal is to have it be 40% VG. I am going to add several ingredients that do not have PG or VG content and I am going to add 50% of these ingredients (exaggerated). Lets leave nicotine out of the discussion.

- Do I add 40 mls of VG (40 / 100 = 40%) and 10 mls of PG to get the resulting 100 mls?
- Is my recipe 60/40? Or is my recipe 10/40?
- Do I add 20 mls of VG (40% of remaining 50 ml) and 30 mls of PG?
- Is my recipe 60/40? Or is my recipe 30/20?
