What I've been doing (and I'm in no way saying you should do the same) is putting everything in the calculator to get the nic pg/vg correct and then just adding drops with their dropper bottles (most of the time). I set the drops to 60 per ml for whatever percentage I want. Works fine for me and it's reproducible if I want. But if you do that, I'd strongly encourage you to see how many drops per ml you get.
