## Abstract

Provided are a system and method of reproducing individual puffs based on empirical data collected by a plurality of electronic vaping devices during use of the vaping devices by users to inhale vapors. The method involves receiving, over a communication network for each of the plurality of electronic vaping devices: (i) reservoir information indicative of a configuration of a reservoir storing a liquid that is at least partially converted into the vapor, and (ii) a plurality of operational parameters for each of a plurality of puffs drawn by the users. The operational parameters include a first operational parameter measured by a sensor system provided to the respective electronic vaping device. An evaluation vaping device is controlled to reproduce a puff by generating a vapor based on the received reservoir information and the received plurality of operational parameters in effect during the puff that is being reproduced.
