I have switched from a 50/50 mix to Max VG, and the resulting flavor is muted. Increasing the flavor from 2% to 2.75% has helped slightly but not enough. Is there a rule of thumb how much more flavoring I need to add to compensate for the increased VG? I can always experiment but it's a tedious process since I vape mostly FA tobaccos, and without an UC, they require at least 2 weeks of steeping. Suggestions would be highly appreciated.
