Yup! You're adding 0.5ml flavouring to 4.5mls of your VG/PG/nic base.

'Tis the only way, really, with "unknown" concentrates. If I have a concentrate that has a "recommended" dilution, I mix one at that strength, one 5% over and one 5% under. If I don't have a "recommended dilution" I mix four samples, 5%,10%15% and 20%. It's not as wasteful as it looks, because, by, after trying them out and confusing yourself with a little maths, you can mix the samples to get where you want to be. ( If you use the same nic strengths, the nicotine content remains the same when you are mixing the samples together)
Write your final concentrate % (the one that you like) down somewhere though! Otherwise you end up starting from the beginning again next time around.

This is where the POTV app comes in handy, I have my preferred mixes saved in there.

I echo what others have said with the samples, I don't make up batches as above I make at X% then adjust with the next 5ml, the reason I do that is to give me a tank+ worth of vaping at said level to give it a good run and see if it settles with me.

When you make up these 5ml samples, how quickly do you vape them afterwards to find out if the flavour % is too high/low?

That's the long piece of string question ... tobaccos I will leave at least a week, 2 weeks if I'm patient ... creamy flavours need a week ... fruits seem good to go the next day, either single or mixes of fruits ... any other kind of mix with 3 or more flavours I will leave at least a week.
I don't vape custards but the consensus seems to be weeks!

Patience is a key attribute for the mixologist. There are various ways to speed up maturation but I don't have the time or inclination for whizzing up with milk frothers, shaking all these bottles every day or breathing them for hours ... suits my lazy nature just to leave them alone for a while and let them do their thing.

I mix juices, try them straight out the bowl, if harsh leave overnight, try again after 24hrs before deciding yay/nay. If nay, leave a week and try again,then if still shite ,leave a few weeks if still shite after weeks steeping, out comes the menthol concentrate and a few drops of that turns any shit into an eye - watering menthol vape.
