The biggest issue I have found is that every mod on the planet is sold with a SS316 profile, and no SS316L profile at all. To add to that, a lot of companies like to ride the SS coils a bit warm, so they dial the TCR up. 316L is apparently a lot more sensitive to the TCR used in the equation when it's in mesh form. I imagine something along the lines of inductance between the individual strands makes it much narrower of a resistance response. Using the 88-93 range, depending on mesh grit, the chipset is focused on the very narrow band that 316L has, and it becomes even better than it typically is with the SS316 plain TCR profiles.
Long and the short of it, people need to ship a specific 316L profile, or VandyVape needs to plaster the TCR on the label, because the L doesn't seem significant if you don't know.
