Personal alpha filter gains over peer filters had a 95% interval that included zero in 42 ds007987 adults. Both methods used personal threshold calibration for later runs within one visit.
We tested the added value of personal alpha spatial filters against filters learned from other people. We used preserved OpenNeuro ds007987 version 1.1.0 covariance data. The primary rule retained 42 adults. Peer fits excluded the test identity. Both methods used personal first-run thresholds and tested later runs within one visit. Mean balanced accuracy was 73.75% for personal filters and 72.04% for peer filters. The mean difference was 1.72 percentage points. Its central 95% interval was -0.21 to 4.65 points. The interval came from 10,000 complete person bootstrap refits that removed all copies of each test identity. The result does not establish superiority or equivalence. The secondary AUC gain was 0.0268, with no multiple-comparison correction. This is an exploratory study on the same cohort with personal calibration and admission based on record quality. The package preserves 172 covariance records, source versions and hashes, code, all draws, figures, independent audits, and reproduction instructions.

We used all 172 alpha covariance records, pinned metadata, and raw retrieval code from this archive. We used its personal filter rule for a new peer-filter comparison. The independent audit also reproduced its primary personal and mean-power accuracy and AUC values. The new question concerns the added value of a personal spatial fit after personal threshold calibration.

We adapted the comparison of personal and peer filters and the complete person bootstrap audit. We tested the method in another cohort after one month.
