Abstract In behavioral and neurophysiological pain studies, multiple types of calibration methods are used to quantify the individual sensation stimuli. Often, studies lack a detailed procedure description, data linearity, quality quantification omit required control for sex differences. This hampers study repetition interexperimental comparisons. Moreover, typical procedures require high number stimulations, which may cause discomfort stimuli habituation among participants. To overcome those shortcomings, we present an automatic with novel estimation method intraepidermal stimulation. We provide in‐depth analysis collected self‐reports from 70 healthy volunteers (37 males) propose based on dynamic truncated linear regression model (tLRM). compare its estimates ( t ) T thresholds mid‐pain stimulation (MP), calculated using traditional standard models. Compared other methods, tLRM exhibits higher R 2 requires 36% fewer applications has significantly intensity lower MP intensities. Regarding differences, were found be females compared males, regardless method. The proposed quantifies quality, minimizes duration invasiveness, provides validation linearity between subjective scores, making it enabling technique further studies. our results highlight importance in
