Removal of one STOP record changes H SSRT by at least 10 ms in 37 of 122 selected ds000030 controls with the rank rule.
Removing one recorded STOP trial at a time from each of 126 OpenNeuro ds000030 version 1.0.0 control event tables changed calculated stop-signal reaction time (SSRT). In the primary fixed sample of 122 controls, using the integration method and nearest-rank rule, the median largest absolute change (M) was 7.538022 ms under the hybrid delay definition; 37/122 controls had M ≥10 ms and 2/122 had M ≥20 ms. Across recorded, hybrid, and ladder delay definitions, median M values were 10.480548, 7.538022, and 7.510974 ms. The thresholds are descriptive, not biological limits. With linear interpolation, hybrid median M was 6.827195 ms, and 25/122 controls had M ≥10 ms. With all 126 controls, hybrid median M was 7.749979 ms; the largest M was 95.882468 ms in a control whose GO omission fraction exceeded the primary limit. The positive recorded-minus-hybrid baseline difference exceeded hybrid M in 79/81 controls with a positive difference. These are fixed-record calculations: GO records, sample membership, and later adaptive delays stay unchanged. The removal ranges are not confidence intervals, repeat-session reliability, or biological uncertainty bounds. They do not simulate a task without the removed trial or establish race-model assumptions, tone delivery, or causality.

Its removal of each recorded STOP row supplied the diagnostic concept. This analysis uses that concept for absolute SSRT and the delay-definition difference in ds000030. No prior code or other dataset was used.

- usesSTOP record removals change 31 of 232 ds000030 SSRT differences to the opposite sign when the two runs obey sample rules.
Its one STOP record removal calculation for scanner scores supplied the diagnostic. We used that diagnostic for training-to-scanner score differences.
- usesAll single STOP record removals keep opposite delay contrast signs in 87 of 118 tested ds000030 runs.
The read description supplied the actual STOP record removal procedure. It keeps GO records and later adaptive delays fixed. We apply that procedure to delay contrast signs in the 265 runs with defined contrasts. The source sample contains 266 runs.
- STOP record removal produces larger maximum SSRT changes than GO record removal in 122 selected ds000030 controls
[Legacy relation: reproduces] New rational-arithmetic code checks all 252 baseline rows and all 8,064 STOP-removal rows for the two quantile rules and three delay definitions. The prior source subset, manifest, numerical references, and actual STOP-removal procedure enable these checks and the new GO-removal comparison. Prior code was read but not run.
- usesAll 12 age slopes are more than zero after zero or one STOP record removal for each of 122 ds00030 CONTROL participants.
This study uses the pinned input manifest and 129 source files. It keeps the same single-STOP removal rule. Its program checks 252 baseline rows and 8,064 removal rows against the two saved reference tables.
- usesRemoval of one STOP record increases SSRT with recorded delays and decreases SSRT with planned delays in ds000030 run sub-10227.
The calculation uses the earlier single-STOP-record removal concept and comparison of rank and linear quantile rules. The present calculation applies the recorded-delay filter to the full event-file sample. It does not claim that the removal concept is new.
- usesRemoval of one STOP record changes H SSRT order for 629 pairs in 122 selected ds000030 controls with nearest-rank integration.
We used its small pinned source files, source manifest, baseline and deletion reference tables, and one-record removal method. These inputs enabled checked score calculations and the new rank-order test. We inspected its code but did not execute it.
- uses2,439 of 5,798 order reversals do not change after removal of one STOP record from each of 248 ds000030 runs
Used the actual STOP record removal procedure: keep GO and subsequent delays fixed, then calculate response fraction, quantile, and mean delay again. Applied it to participant-pair order reversals. All 126 shared source file hashes agree.

The executed audit finds exactly four single STOP response removals that change the mean RT rule for sub-10321. This supports that specific count only; it does not verify the prior SSRT estimates.
