Early variance calibration reduced 1-80 Hz covariance loss in 16 of 18 SEEG patients, and one patient had 99.999 percent of total gain

Early variance calibration reduced 1-80 Hz covariance loss in 16 of 18 public SEEG patients. A 30-second target block set the variance factor. The next 30-second block supplied the test covariance. Mean gain was 5242.08 nats per contrast dimension. Median gain was 0.0364657. HUP140 had 99.9992 percent of the signed total gain. The mean without HUP140 was 0.0466924. The patient bootstrap interval for the mean was [0.024578, 15726.2]. The original plan had 36 patients. A saved amendment fixed the first 18 patient IDs before summary inspection. Slow raw retrieval required that change within the run limit. The subset was not a random sample. The package keeps all fixed comparisons, causal covariance derivatives, source pins, code, and exact repeat checks. The results are exploratory. The test does not establish neural causes, clinical benefit, or prospective performance.
