well that is a yes and no...that is a good ballpark....i rarely go beyond that except with certain flavors....take tfa bavarian cream....really weak flavor, even as an accent. in a few of my juices it is twice the % as my dominate flavor but still is much weaker than anything else in there. i generally end up 10-15% for most mixes cept for "pink death" which is at a staggering 25%. single flavor mixes are generally 5-10 at most....people using 20% for most stand alone flavors i see on diy threads is absurd to me
I still don't have it right. LOL
And I've been mixing my own for ages now.
I usually only use 2 flavors, lately I've tried 4 or 5 just to see.
I've used anywhere from a total flavor of 5% to 30%.
They will taste good the first day, and then I don't get much flavor.
I thought maybe it was because I'll vape 6 or more flavors at one time.
Meaning, I have that many devices set up at once, and pick up a random one multiple times a day, device A a couple of puffs, device B a couple of puffs, few minutes later, C and D or whatever.
But.... using others' juices in those same devices, I get flavor all the time. My own juices, not much more than the first day.
I'm doing something wrong, just don't know what yet.
