So once again... I do that "Number in my Head" thing.
If I have 100% VG Nicotine Base, and I want to make a 15%PG : 85%VG Final Ratio mix, the PG has to come from Somewhere. Right.
So then I look at my Flavoring. And Most Flavoring is PG Based. So I ask myself, "How Much Total Flavoring am I thinking about using?" 15%
Cool. So if I add 15% Flavoring, and Most of the Flavoring is PG, then that would make up the 15% PG in my final 15%PG : 85% VG mix.
Then I put the Numbers in my Calculator and Binbgo Bango... the Recipe just calls for VG Nicotine Base, Pure VG and Flavoring (which is PG Based). All the PG Needed to make 15%PG : 85%VG
e-liquid comes from the Flavoring.
And that Matches what the Calculator said you should do in Post #7.

Now if you want to make a Final Mix that has More that 15% PG, like say 30%PG : 70%VG, you are going to have to add some PG.
Because there Isn't Enough PG in the Flavoring to get you to 30% PG with the Amount of Flavoring you are going to add. And you Can't Add 30% Flavoring (which would get you to 30% PG) because that would be Way Too MUCH Flavoring.
And it would Taste Awful!
