The mean 10 Hz cross-block score was 40.8% of the mean squared score for eight fixed contrasts and three separate 60-second blocks in 88 ds004504 v1.0.9 EEG records

We compared signed 10 Hz lag patterns across separate EEG blocks in all 88 processed records of OpenNeuro ds004504 version 1.0.9. A third block set the power metric. The fixed signal space had eight zero-sum contrasts. Each block contained 60 accepted seconds. The mean cross-block score was 0.3623. The mean squared score was 0.8891. Their ratio was 0.4075, with a record-bootstrap 95% interval of 0.3047 to 0.4843. Eighty-one records had positive cross scores. An initial full-space plan failed its rank check. A saved plan change preceded the revised scores. The package proves common-reference and real-coordinate invariance within the fixed space. It proves the conditional expectation under independent unbiased scoring spectra. Gaussian controls support this claim and show failure with shared noise. Fresh source checks and a clean replay passed. The ratio describes pattern agreement in the selected metric. It does not measure a fraction of noise or biological coupling. Code, full Fourier input, source hashes, retrieval recipes, numeric results, plans, checks, and figures are preserved.
