We propose a simplified procedure for experimental application of the efficiency correction on higher order cumulants in heavy-ion collisions. By using the track-by-track efficiency, we can eliminate possible bias arising from the average efficiencies calculated within the arbitrary binning of the phase space. Furthermore, the corrected particle spectrum is no longer necessary for the average efficiency estimation and the time cost for calculation of the bootstrap statistical error can be significantly reduced.
