Would you guys say they’re pretty accurate with their flavor % suggestions or does it tend to be heavy/light or just all over specific to flavor?.
Flavoring required is a very subjective thing. It depends on your taste buds. It also depends on what it is being vaped in. A subohm DTL tank usually requires considerably less flavor than a MTL device with lower vapor production does.
The % they recommend is usually but not always on the high side at least for my tastes. It isn't really a good idea to mix a large quantity of anything that you haven't tested out. If you don't like it, you are stuck with a lot to suffer through or throw out. It is better to test small quantities starting at a low percentage of flavor to see what you get and go from there. Once you get it to your liking, you can mix large quantities
Some flavors are vapable right after the mix and some need time to bloom. Some require a few weeks of steeping.
