I couldn't figure out why the calculator kept coming up with negative numbers if I combined pg/vg/flavors/24mg nic with wanting an end result of 24mg.
Idk why it took longer than a second to figure out my problem. I must have stared at the negative pg numbers for an hour or two without realizing my problem.
I did that too. I almost emailed the developer of the app I was using to tell him that his code was messed up.
I know that I still get confused looking at PG vs VG, ie using the PG number for the VG amount and vice versa.
