Each of 19 tested SEEG records had a pooled beta coherence leader change after fourfold group copies with fixed signals

Complete copies of one contact name group changed the top pooled group in each of 19 selected SEEG records, with fixed signals, pair scores, and known group identities. Every record had at least one change among its group copy tests. The mean patient change rate was 35.7% for four copies (95% patient bootstrap interval, 26.3% to 45.6%). Equal group means stayed unchanged under complete copies. Across adjacent minutes, mean Spearman rank agreement was 0.8172 for equal group weights and 0.7839 for pooled weights; the paired mean difference was 0.0334 (95% interval, 0.0034 to 0.0605; exact two-sided sign-flip p=0.03918 under independent-patient and symmetric-null assumptions). Both rules repeated the top group in 14 of 19 patients. This selected cohort does not establish a clinical benefit, anatomical validity, correction of missing brain coverage, or generalization to other patients or implant types.

usesFour copies of a contact group in the common average changed early gamma rankings in 27 of 28 selected SEEG patients
Uses its complete-copy result as method context. This prior study was read after the local plan was saved. The present test concerns reference weights and clinical gamma rankings. Its data and code were not reused.
Independent code reproduced beta shaft weight results in 19 SEEG records; group selection changed the estimated rank agreement gain
[Legacy relation: reproduces] Independent code reproduced the matched group identities, 800 score rows, ranks, all 2,400 copy outcomes, full node matrices, bootstrap intervals, and exact sign counts. The original analysis used a different group rule and squared imaginary coherency. The new package adds exploratory group selection comparisons in the same 19 patients. It does not claim a new weighting principle or validation in new patients.
