I can see why no one has wanted to touch this one
But I’ll give it a try!
First, you DO NOT have to use PG if you don’t want to, I don’t. I can’t think of any calculator on ELR that “forces” you to put PG into your recipe. Take ELR for example, you can check the box that says, “MAX VG” and boom…all VG
Now lets take your equation up top, which I fully don’t understand but I can see you are making a Strawberry-banana recipe, using only VG,2 flavors and water? No nicotine? Personally I have never used water in any of my recipes and never saw the point but that’s just me.
You are going to have to give us more information before anyone or myself can fully help you, like what company makes the flavors you are using? This is important to figure out the right %s of flavoring because as much as we would like to just throw a little of this and a little of that and have a nice juice…it doesn’t work that way. Each company has it’s own strengths and weaknesses when it comes to actual flavor taste and potency.
Also we need to know how you are measuring your ingredients? Syringes/pipettes/beakers/flasks/measuring cups/eye/weight? All these are important and I would suggest using a scale for the EASIEST and fastest method but syringes/pipettes would work too
But back to the ELR calculator…
Select create a new recipe and under desired strength put a zero(0) and under nicotine strength zero(0), since you will not be using any nicotine. Then click “add flavor” and type/select your flavor/company then the % you want.
Below this you will see the finished recipe and you do not have to do any math what so ever. The problem is, there isn’t any golden % for a flavor, trial and error my friend but I will say any banana flavor will be a lot stronger than any strawberry, so maybe start with 10% SB and 5% banana, personally I would not add water…but again, not enough information to help you here.
Otherwise use the search feature on this site, it is very helpful!
