Sometimes they are hopelessly out on what is required - in both directions. It is a lot easier to add concentrated flavour than faff around adding base and dilutents. Apart from tobaccos, I will always add 2.5% ethyl maltol to my base - this smells like candyfloss but sweetens very little - what id does do is 'pop' flavours - sometimes this is very pronounced - things that are flat or dull come to life with it. On eliquid base - I buy the 52 mg PG base from cig-eliquid and cut it 50/50 with his aqueous VG. This gives me a base of 26 mg per ml. I mix with this and most of my final product comes out in the 17- 24 mg / ml region typically at about 70% PG to VG ish. Most of the concentrates you get will be PG based and my ethyl maltol crystals I mix in PG too. VG tastes sweeter, but is thicker and slightly less good at flavour absorbtion - it gets there but usually I find it needs a longer steep and a little more concentrate. You can dilute it with either deionised water (pharma or food grade) or vodka, which helps. I like vodkaa as it adds a
