Set-winning probability estimation discrepancy (SWP-ED) of participants in the first set across five score categories. The red dotted line indicates perfect estimation without any discrepancy, whereas estimation above indicates over- and below underestimation of the SWP. The SWP-ED is calculated as the difference between a participant’s SWP estimate and the empirically calculated SWP for the corresponding score. Independent t-tests or Mann-Whitney U tests were conducted for group comparisons within each score category. To account for multiple comparisons, a Bonferroni correction was applied, adjusting the significance level to α / m, where m is the number of tests conducted per score category. Significant results are marked with asterisk (*, p < .05 / m), dagger (†, p < .01 / m), or double dagger (‡, p < .001 / m).
