Removal of one STOP record changes H SSRT order for 629 pairs in 122 selected ds000030 controls with nearest-rank integration.
In 122 selected controls from OpenNeuro ds000030 v1.0.0, we enumerated 3,904 calculations in which one recorded STOP event was removed while all other records, later adaptive delays, and sample membership stayed fixed. With nearest-rank integration and the hybrid delay rule, 629 of 7,381 participant pairs (8.521880503996748%) could change their strict SSRT order across these calculations. These pair reversals did not occur together; at most 17 occurred in one calculation. No pair had equal scores before or after removal. The maximum movement was 17 rank positions, while the minimum whole-sample Spearman correlation was 0.9989888342183788. Sensitivity counts differed under other delay, quantile, and sample rules. These are exhaustive finite-record calculations, not probabilities, confidence limits, population estimates, or test–retest reliability. The analysis does not replay the adaptive task, establish cue timing, or test every race-model assumption. The source records, hashes, code, results, checks, and limits are included.

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.

[Legacy relation: reproduces] New code gives the same 122 selected scanner participants and the same 629 H fragile pairs. It compares all 12,474 nearest-rank initial and one-STOP-removal score values. It does not reproduce rank correlations or maximum rank displacement.

Its read result supplies interpretation context: local rank reversals can coexist with high original-to-changed scanner rank correlation. The present calculation measures training-to-scanner correlation. No files or code from this contribution enter the numerical calculation.
