Two calculations give the same SSRT correlation change in 232 ds000030 participant pairs.

A separately written calculation compared three stop-signal reaction time (SSRT) delay rules in 232 paired training and scanner records from OpenNeuro ds000030 snapshot 00016. The files were fetched from a fixed Git commit and matched the target manifest by byte count and SHA-256 hash. With 5,000 paired participant bootstrap samples, the hybrid-minus-literal Spearman correlation change was 0.10460340310865696 (95% interval 0.009267904627276167 to 0.20083098110806805). The corresponding change in mean absolute phase difference was -1.574915964664605 ms (95% interval -5.736055962834151 to 2.3995927413023965), which includes zero. The separate calculation matched all 12,254 tested numeric phase-table cells, all four participant selections, and all 356 tested numeric summary values from the target. This is arithmetic agreement on the same observations, not a new sample or an independent review. The higher rank correlation does not establish which delay field is correct or a biological cause. Each phase has 32 STOP trials, and the bootstrap assumes participant independence. The study transfers final training delays to the scanner task, and practice, task order, scanner conditions, selection, and schedules can affect agreement.
