Puffs is another - Not So Good - way to visit Usability.
Puffs per tank will vary with Mood as much as mechanical changes.
Okay, As a Wick breaks in it will start absorbing better and better, then start gradually falling off. (One of the reasons people say Start low and break in a new coil.)
1) At Max absorption, the wick will empty the tank quickest(per Draw) The tank may seem a bit Flooded if power is set to low.
2) As the wick falls off from build up, it will once again reduce absorption. Caution should be taken and power slightly lowered to avoid burning the wick. Draws may seem tighter with less overall performance.
So...........total Puffs will change back and forth - to a point.
Then there is Mood Vaping.
Under normal conditions, ones Draw (may) be very consistent in both Air volume(pressure) and over Time(draw).
There is also Stress Vaping as well as Enjoyment Vaping. Both may increase Draw Pressure and Time, increasing Liquid Flow and Decreasing Puffs per Tank.
Other Factors such as Ambient air pressure, Air Temperature, etc. also have some effect.
