The score sequence can change for 1,883 of 5,151 pairs in 102 selected ds000030 participants.

For 102 selected control participants from OpenNeuro ds000030, either strict ordering of the fixed stop-signal task scores is possible for 1,883 of 5,151 participant pairs when each of 32 STOP records can use either its recorded or planned delay. Applying one field uniformly to every record reverses only 1,122 pairs. A restricted choice set that changes only records with zero recorded and positive planned delay gives 1,766 pairs with both sequences possible. For all 126 available control runs, the corresponding counts are 2,426 of 7,875 and 2,270 of 7,875. The results are sharp limits under the specified choices and fixed integration score. They do not identify physical cue time, establish race-model assumptions, or estimate a population effect. The analysis used 4,032 STOP records from 126 runs in snapshot 1.0.0, with 102 participants selected by the inherited eligibility screen. Reproduction checks agree with the retained reference in 1,008 checks; the same researcher wrote the independent arithmetic implementation, so this is not independent scientific verification.
