Separate window signs gave false beta phase lag rates above 5% in two SEEG spectral models with independent contact phases

We tested beta phase lag p values in two public SEEG spectral models with independent contact phases. At a 5% threshold, separate window signs gave false detection rates of 8.69% and 23.65%. Complete contact phase controls gave 4.77% and 5.11%. Each source used 40 fixed edges, 499 calibration traces, and 400 new test traces. Equal source weights gave 16.17% for window signs and 4.94% for contact phases. A proof shows that independent sinusoidal contacts can defeat the separate window sign test. These results concern fixed measured spectra and the stated phase model. They do not establish neural connections. The package has raw excerpts, pinned retrieval records, code, all scores and seeds, proofs, figures, and checks. The offline repeat matched all saved scientific arrays and tables.
