Cliffy, do you taste test your juices at the time of mixing? I get 90 - 95% of final taste in my juices at time of mix. They will either improve with flavor blending, which I can usually detect at time of mix, or they won't (only the vape gods know why). Most will improve with flavor blending, and reach maturity in 24 to 48 hours, but you can tell how good the mix is initially, at least I can, and I don't need to wait for days to tell if something is going to be good. I test mix using the 100DT, which gives me about 2.5ml's, enough to vape in a small tank, and I'll usually make a mix and then vape the tank, unless it's not good, or not right, in which case I just pour the tank out, remix and go again. In this way, I'm vaping 90% or so juice at time of mix. By experience, I have a pretty good idea what this 90% juice is going to taste like a day or two later. In fact, once the bubbles leave the mix (usually within 2 hours), most flavor bonding is done, and then you have a 95% mix. This only works with high flavoring percentage mixes, which do not require long steep times. So, I write this just to clarify the method I use, because it doesn't take days to know whether I have a good juice mix or not.
Using the 100DT, I can change my starting percentages in less than 5 minutes with a new batch. In this way, I can usually find the sweet spot for primaries within ten or fifteen minutes, regardless of mix complexity. This method works....for me, anyway. I do know what my juice is likely to taste like two days from now. Just sayin'.
A lot to wrap my brain around. Got order coming for all the suggested starter flavors in sample size for 100DTs, TFA account set up for bulk purchases, and ready to learn by mixing 
As I was reading through the posts and the rules of thumb I was wondering are there any rules of DON'T DO THIS
