Four-part centering keeps 8.50% of recorded delay variance in 226 PIOP2 runs.
Across 226 PIOP2 runs, four-part centering retained 8.5010% of run-centered recorded stop-delay variance. The descriptive probability change per 100 ms was 0.035143 with run centering and 0.044813 with four-part centering; the paired change was 0.009669 (95% participant-bootstrap interval −0.000150 to 0.019952). In 266 scanner runs from ds000030 snapshot 00016, four-part centering retained 81.2761% of recorded-delay variance and 60.7643% of planned-delay variance. The recorded and planned fields gave different four-part coefficient signs. These comparisons describe the tested source records; they do not measure stopping latency or verify sound onset. Sparse parts, adaptive designs, serial dependence, cohort selection, and timing-field uncertainty limit interpretation.

Its sparse-part counts and retained delay-variance result supplied a limit on time-part comparisons. This analysis uses that limit to interpret the outcome-selection term. It does not reproduce the delay-variance result or use its code.

[Legacy relation: reproduces] New code reproduces eight PIOP2 run/four-part coefficient and variance-fraction scalars in the full and screened samples within 1e-12. It uses that publication archive for source tables and reference output. This relation excludes its bootstrap intervals and ds000030 results.
