I just did the math, and that's roughly 3.2% you're using. I haven't started my DIY yet, but that seems pretty low compared to what I've read of 5-10%. I'm even a little more unsure about what to do w/ the flavorings I ordered from Vapor Shots. For their natural flavors, it says that they're not as strong, and to *start at 20%. I thought that sounded insanely high, but after reading around, it's not all that uncommon for some flavors. The 1st batch I wanna make is blueberry / vanilla ice-cream, and both flavors advise the 20% total, so I was planning on doing 10% of each. I have no idea what to expect, but I will kno how it compares to the B&M's stuff, and I'll start making adjustments from there. My package (2 day priority) was due today, but has been backed up due to the huge snowstorm in the northeast, bah!
