I'm still waiting for my e-cig (they sent me the wrong one) so I haven't actually tried this yet.
To prevent waste when sampling new flavors, a formula for how much liquid needs to be added to 1 drop of flavor for a given percentage will hopefully be handy.
Enter into WolframAlpha or another graphing program: plot VGPG = (
.04/P)*(100-P),
P=0 to 25.0
WolframAlpha graph
*The
Flavor % is on the horizontal line(X) and the
mL to add is on the vertical line(Y)
*
.04 is the mL per drop. This is based on 25 drops per mL. With the pipette I used and my shaking hands, I got 28 drops per mL, so I used 1/28 or .036
*
P=0 to 25.0: this is the percentage range to graph. If you're only interested in 3% to 10%, change this to
P=3 to 10.0 for a more accurate graph.
Example: For 5% flavor, add 1 drop of flavor to about .77mL

Or for more accuracy (using
P=3 to 10.0):

Hopefully, I'll be using this by the end of the week. Now, I'm just staring at my E-Juice supplies
