Within runs, total reproduction had less relative variation for three intervals than one at matched nominal totals in 23 ds006720 adults
We compared variation of total reproduction for one and three intervals at matched nominal totals in OpenNeuro ds006720. The analysis used 6,539 trials from 23 adults. We removed run means and gave people equal weights. The geometric ratio of standard deviations of log total was 0.791. The 95% person bootstrap interval was 0.736 to 0.849. All fixed supporting checks had the same direction. An added description of variation in seconds was uncertain: ratio 0.988, interval 0.907 to 1.086. Mean reproduced totals differed. Item variation had the opposite direction under a different adjustment rule. The result concerns relative total variation in this task. It does not show improved memory or a neural mechanism. The package preserves source files, code, provenance, trial decisions, all bootstrap draws, and independent checks. A fresh source download gave the same numerical results.

We used its nominal target map, author source files, target anomaly location, and author response match records. We adapted its restricted R table reader and reused its licensed parser subset. The new contrast compares total variation between one and three intervals.

We used its pinned source event copy and retrieval manifest. Its trial selection rules informed the new total variation analysis. We checked source hashes and retrieved every source file again.
