Some of my mods have puff counters, but I've never paid much attention to the count. We vape our juice according to what it takes to satisfy at a given nic level and ignore the rest of the stats. It's all about nic satisfaction.
I judge my vaping by the amount of juice I vape in a day. At 10 watts I vape a tank and a half of unflavored, 3mg/ml, 50/50 pg/vg/nic per day in a Kayfun atomizer. It's a pretty low nic/juice rate.
i started with 24mg/ml nic in 2010 and tapered down over time. These days I'm vaping much less juice per day at 3mg strength.
