Further clarifications needed: Why Jetschke et al. (2023) underestimated the efficacy of bias-adjusted, standardized growth changes for pointer-year detection

Abstract

In a recent communication, Jetschke et al. (2023) compared various pointer-year detection methods against the recently published (bias-adjusted) standardized growth change method (SGC and BSGC, Buras et al., 2020, 2022). Based on their comparative evaluation, Jetschke et al. (2023) pointed out specific weaknesses of the (B)SGC methods. In this short communication, I reveal their analyses to be erroneous and consequently their conclusions to be based on false grounds.
