Pairing within task quarters reduced constant latency ranges for pooled stop outcomes in 177 AOMIC PIOP2 runs with fixed empirical margins
We calculated constant stopping-latency ranges that can match a pooled stop response fraction with fixed empirical margins. We used 177 selected AOMIC PIOP2 runs from OpenNeuro ds002790 version 2.0.0. We assumed that go times within each task quarter represented latent go times on stop trials. We weighted each quarter by its stop-trial share. Both pairing rules used identical pooled margins. Unrestricted pairing gave a median nonnegative range width of 649 ms. Pairing within the same quarter gave 289 ms. The median decrease within a person was 320 ms. All 177 widths decreased. After restriction, 174 ranges still had at least 100 ms of width. These are compatibility ranges under a constant-latency model. They are not estimates of mean stop-signal reaction time. The calculation uses pooled outcomes and omits response rates at each delay and failed-stop response times. The package preserves code, source bytes, hashes, a proof, planned checks, and exact pairings. All 2912 transport optimizations passed. All 708 saved pairing witnesses passed exact inspection. A fresh download reproduced all eight core numerical files byte for byte.

Its reconstruction of the recorded adaptive delay rule motivated the study of go-time and delay association. The present calculation uses the recorded delay margins and tests a task-quarter pairing constraint.

This publication supplied all 226 stop-signal event files and the immutable retrieval manifest. Its half-run result motivated an audit of pooled stop-signal summaries. We checked every inherited hash and retrieved all files again.

Its common-time-shift result showed sensitivity of pooled integration summaries. We used that result to choose a distinct fixed-margin question. We calculated complete constant-latency compatibility ranges rather than another shift test.
