Thanks for the help on this.
When I enter my nicotine base values should I just put 100%vg/pg or should I subtract the nicotine content which I am assuming to be 7.2% (giving a nicotine base vg/vg percentage of 92.8%?). When I do this on e-liquid-recipes calculator it automatically adds the remaining percentage as VG rather than acknowledging the remainder as nicotine content
