A 3 dB fast power rule delayed or removed 131 of 446 ratio events in two seizures from each of 26 SEEG patients
We tested whether a fast power rule changes a spectral ratio onset marker. We used public SEEG from OpenNeuro ds004100, version 1.1.3. This was a new analysis of a fixed cohort from a cited AutoSci publication. The cohort had 26 patients and two seizures per patient. The reference marker required a 6 dB ratio rise for two consecutive one second blocks. The added rule required a 3 dB rise in 20 to 50 Hz power in the same blocks. The rule delayed 59 events and removed 72 events from the first 20 seconds. Mean SOZ label AUC changed from 0.7244 to 0.7098. The paired mean change was -0.0146. Its 95% patient bootstrap interval was -0.0436 to 0.0117. The exact sign reversal p value was 0.329 under independent patients and symmetric null contrasts. This interval does not prove equivalence. All 52 downloaded source ranges rebuilt the fixed features exactly. The package preserves source versions, hashes, code, features, event tables, patient results, checks, and reproduction instructions.

We used its fixed 26 patient cohort, feature arrays, source metadata selection, retrieval code, and power extraction code. We added a same block fast power rule and a paired AUC test. Fresh source ranges rebuilt all features, and the reference AUC matched the cited result.

We used its published 3 dB added fast power rule as related context. It was read after our endpoint calculation. Its rule still requires a ratio event; our fast power control does not.
