This was 20 drops in 10ml which is 10%, right?
20 drops per ml might be the default setting in one or more of the joose-mixing programs, but I believe you can change it to however many drops per ml you want.
I was using nothing but MBV flavorings in the 15 ml dropper-top bottles for a while, and for those particular bottles with that particular density of contents, it took 37 drops to equal one ml.
I don't much care for using drops as a measurement. No criticism intended of those who find mixing by drops easy and convenient. It really only becomes an issue when you've just created the best joose ever made and want to make a much larger quantity in exactly the same proportions. For small quantities I use this 10 ml graduated cylinder, and it's great. It has embossed marks (can't rub off!) every 0.2 ml.

Regardless of the measuring container used, measure to the meniscus of the liquid being measured. That's the lowest point in the middle of the concave surface of the liquid, which is more of a pronounced difference with thick liquids than with thin.
When I am experimenting and making small batches (100 drop tests) I will use drops, but make sure all the drops are the same. When making a final recipe (10 ml or more) I use syringes. Maybe a pipette for vg (mls, not drops)
I usually mix 60-120ml at a time per flavor so a "pinch" isn't that much. I keep swearing I'll try more complicated recipes but I never do. At least I'm happy with what I make and think that's what counts for everyone. I should add, part of my lack of enthusiasm for new flavors is having severe food allergies and with labeling standards on flavors, a mistake could cost a couple thousand dollars or my life. Simple Simon in this case is pure self preservation. But I love hearing about other people's adventures in mixing.
That is a heck of a thing to be dealing with, and makes me realize the importance for manufacturers to have complete and accurate disclosure of ingredients.
I use graduated cylinders for all of my diy. But nearly everything I make is either 30ml or 4oz/125ml batches. For testing I do 3ml batches and use syringes for that.
Just got some DIY WTA, very thick. Going to be working with that this weekend. Probably going to take a little playing around with to get it to wick with my normal 50/50 PG/VG mixes. Probably going to try thinning with distilled water and another batch by adjusting the PG/VG ratio.
Good luck with it!! and where did you get your diy wta? Mentioned this to my SIL earlier, would like to see if I can get her to try it
Somebody here actually makes their own WTA. I think I might remember who it is but instead of guessing wrong I'll just hope she (I think) says something about it.
I do the 100 drop test to test.
Currently making 100mls at a time got four 100ml bottles on the go.
Use syringes and needles for the 100 drop.
Only do it once to see how it is then decide if any changes are needed, some people I think fine tune it with many tests before full scale.
I am so happy not to have the above-normal number of taste buds that super-tasters have! I know what tastes really good but it is really nice not to be very aware of what tastes really bad!*
I know some FA flavorings are concentrated and some aren't. Some use 3% some 10-15%
*One of a small number of exceptions that proves the rule: Do not, repeat DO NOT, use FA Coffee Espresso at anywhere NEAR 3%. That's WAY too much. I've now had to turn a 100 ml batch into a 250 ml batch to reduce the 3% of FA Coffee Espresso I used, and it may well turn into a 500 ml batch before the percentage is reduced sufficiently to be palatable, even to relatively tasteless me!
Other flavorings which I like and use but which I will always use at 1% or less: TFA Tobacco Absolute (Pure), Vaping Zone Superconcentrated Klondike Tobacco, TFA Absinthe and TFA Jalapeno.
