Let me clarify again:
I am asking if there is a standard, or, general value for "max vg". That I am only curious about because my juice seems to always be in the 80/20 range, which I have NO problems with vaping, juice flow, or vapor production.
I was just curious to know if there was a value that was standard for when someone says "max vg".
As far as "extra flavor", there too, only curious to know if there was a "general value" that is added to the base values. Obviously for people that DIY, that value could be solely dependent on that person's tastes, but, in shops, is there a blanket percentage value added when someone asks for "extra flavor"?
For example, a local shop where I was getting "banana cream pie", I was asking for "extra flavor" because the "standard" values did not give me that strong banana flavor that I like. So if their standard value for the Banana cream flavor concentrate is 3%, then me asking for "extra" is adding what percent more to the 3%.
Finally, I'm not trying to be an ... here, but I thought my first post asking these questions was quite simple.
