E.g. I've used time of max percap as a lag time proxy
This paper (Zwietering, M. H., F. M. Rombouts, and K. van'T. Riet. "Comparison of definitions of the lag phase and the exponential phase in bacterial growth." Journal of Applied Bacteriology 72.2 (1992): 139-145.) and this paper (Reiter, Michael A., and Julia A. Vorholt. "Dashing Growth Curves: a web application for rapid and interactive analysis of microbial growth curves." BMC Bioinformatics 25.1 (2024): 67.) also cite another definition of the lag time which is the point when the derivative of the percap derivative (via log-transform) is at a maximum (i.e. the percap deriv increases the most rapidly)
