The 95 percent interval for practiced minus new sequence timing gain included zero in 24 ds006502 adults after one day with fixed personal weight 0.5

We tested whether personal training timing helped predict the same 3–2–4 movement more in a practiced sequence than in two new sequences. We used OpenNeuro ds006502 version 1.0.0. Twenty-four adults met the fixed next day rules. The personal weight was 0.5. The practiced minus new sequence gain was 0.09108 squared log-ratio units. Its person bootstrap 95 percent interval was -0.02073 to 0.25635. The interval included zero. The test did not resolve greater practiced gain or establish equal gains. A fixed influence check reduced the contrast to 0.02923 after removal of one adult. A later visit check had an interval above zero, but it was secondary and used different controls. We proved that the equal-person gain contrast equals a scaled covariance of training timing with the target difference. All 291 small source files passed fresh download checks. A separate parser and scalar audit passed. All 69 analysis files matched a full fresh-source run. The package preserves data, code, provenance, predictions, random draws, proof, figures, and run instructions. Position, task order, correct-cycle selection, and few control cycles limit inference.
