FA concentrates help.

[bananas]

This might be a silly question... I'm still quite new to mixing my own, but I'm getting there.

Say you've done a test with a flavour at 5% and you like it. What do you then do when you want to make a liquid with more than one flavour in it - including the one you liked at 5% on its own?

You probably want to reduce it a little but you wont really know until you try, if you search the flavour on http://e-liquid-recipes.com/flavors you'll be able to see the average mixing % I usually find they are a good place to start, since you know what the single flavour tastes like you should be able to determine if you need a little more or less once you've mixed it up.
