Replacement of zero delays gives 101 smaller and 101 larger absolute phase differences in 232 ds000030 pairs
In 232 screened training–scanner pairs from OpenNeuro ds000030 version 1.0.0, replacing recorded zero stop delays with positive planned delays produced 101 smaller, 101 larger, and 30 unchanged absolute phase differences. At the descriptive 50 ms task-step cutoff, the count at or above the cutoff rose from 72 to 81; the mean absolute difference changed from 45.5075 to 43.9326 ms. The paired bootstrap interval for the mean change was −5.6437 to +2.4128 ms and included zero. Thus the observed counts do not establish a population increase or decrease. The analysis used literal, hybrid, and nominal delay fields in 232 primary pairs and 265 estimable pairs. The phases share transferred delay starts, and the files do not provide measured sound onset. The 50 ms value is a task step, not a clinical acceptance limit; the result does not identify a correct physical delay field or biological cause.

Its estimator, paired screen rules, and reference tables define the comparison. New code matches the 232 primary IDs, 1593 defined phase scores, and 1064 phase flags. The new counts and cutoff comparisons extend its unresolved mean absolute difference result.

We used 532 paired event tables, two source information files, and the source manifest. Their source and publication hashes agree. Its history mismatch identifies sub-10855, which the new primary screen excludes.
