When I run into those extra strong flavorings, I take a couple of mils, and dilute it with a couple mils of PG.
It makes it a lot easier to work with. I don't dilute the whole bottle, as I may want to use some "as is" in large mil recipes
Bill and I don't see eye to eye, you and I do, but I do see his side of it too.
Problem with his way (for me), is I just don't mix and vape.
When I mix, I usually mix 20-30 bottles (up to 6ml each), at a time, of all different flavors.
I don't have time to mix just enough for the day, because I rotate 8 mods daily, each with a different flavor.
I do not have an ADV.

So .. everything ends up being 4-6 weeks old before I get to it to start with.
When I've got about months worth left, I mix another batch of different flavors, and it go's to the back of the line.
I stay at least a month ahead of myself at all times, never "fresh"
All these were pre-tested in small amounts, after steeping, so I know they are good, or I've adjusted them so they would be good at a ripe old age.
There is no way I could have a large variety of flavors and recipes around without them naturally getting steeped, since I mix so many at a time, and only mix about once a month.
I guess my way of doing it all began when I first started vaping, because I started with tobacco flavoring (like most), and I knew they needed 6-8 weeks of steeping, so everything else automatically got it too.
I know people that mix and vape, because they vape the same thing everyday.

I'm just not going to mix up 8 different flavors every morning, to keep the variety I like going.
And yes, I like my flavors steeped, because to me, time gives them a chance to "do their thing"
So, Bills right for the mix and vape group, ... I'm part of the mix and steep group.
I love this thread, as I've found a lot of good recipes, even though I do them "my way", and stick to less than 20% flavoring.
I just don't contribute much since I'm on the other side of the fence, as to how it's done here.
Bill's helping a lot of people learn about DIYing, but like he says, to each his own.
We've butted heads a few times, but he hasn't chased me off yet
