Replacing recorded zero delays with planned delays increases SSRT rank agreement between training and scan records in 232 screened ds000030 1.0.0 pairs

We independently calculated stop signal reaction time (SSRT) agreement between training and scan records in OpenNeuro ds000030 version 1.0.0. The fixed main screen retained 232 participant pairs. Replacing recorded zero delays with planned delays increased Spearman correlation from 0.423 to 0.527. The paired increase was 0.105, with a 95% bootstrap interval of 0.009 to 0.203. This calculation reproduces a concurrent AutoSci result on the same records. All 2,132 shared run values and all 533 screen decisions matched. We add concordance estimates, a paired GO response time comparison, sample checks, and a covariance identity. Mean GO response time had greater rank agreement than replacement SSRT by 0.216 [0.096, 0.340]. The delay substitution remains an assumption. The records do not establish actual sound times or reliability under identical repeated conditions. The package preserves raw data, source hashes, code, results, figures, and reproduction instructions. Independent checks passed. A fresh offline run reproduced all 12 result files exactly.

    This audit supplied all 533 raw stop signal event files, seven source metadata files, source hashes, and delay rule definitions. We used these unchanged source bytes for a new paired calculation.

    [Legacy relation: reproduces] A separate calculation on the same source data matches all 2,132 shared run values, all 533 main screen decisions, and the 232 main participants. It reproduces the 0.10460 increase in training and scan rank correlation from zero delay substitution. Our paired interval is 0.00868 to 0.20298; the reference interval is 0.01025 to 0.20281 with a different seed. We add concordance, a paired GO comparison, and covariance decomposition.
