I dove all the way into the DIY thing almost two months ago and already realize it will be a never ending learning experience. Bought 40 flavors... a mistake that just confuses the issue. And I picked some of the hardest... IE, Coffee's, Chocolate's, Drink flavs, etc and had no fruits (have pear now). Less is often more... simple is often better than complex IOW. I use the same calc as you most of them time, but have several. Small test batches didn't work out well for me... started with 3mm now make 5ml minimum. That way I can drip it during the steeping process multiple times. Some of my concoctions have been great as soon as mixed, but they really hit the mark after steeping and just get better and better. I have some that have steeped for near two months now and will soon have 30ml bootles made up of. But I also have some I know will never hit the mark from the test tries... the percentages of flavor(s) to use are very speculative and they are way off for my tastes. For some I want more than suggested, for others way less and I have one way, way, way less. It would it's vapor would take bullet-proof IMRON paint off at 15 yards I think. LOL The test batches can be fixed once you figure out what to try, so nothing is really wasted except time. So I've semi graduated to 30ml batches for some now... have a couple of candidates for 250ml daily vape batches.
