Mean overlap of selected FRandR channels was higher with full record references than with separate halves in 136 sleep SEEG records from eight patients

We measured agreement between selected FRandR channels in public sleep SEEG event tables. FRandR means fast ripple marks that occur with ripple marks. Eight depth-only patients supplied 136 complete 300-second records and 23,779 FRandR marks. Mean overlap was 81.52 percent when each 150-second sample was compared with its full record. It was 65.67 percent with the other half. The difference was 15.84 percentage points, with a descriptive patient bootstrap interval of 9.40 to 26.23 points. This comparison changes both shared data and reference duration. An added comparison held reference duration at 150 seconds and shared 75 seconds with the sample. Its difference was 12.89 points. A set bound shows that the equal-half contrast has a structural direction when neither half has a selection boundary tie. The planned sign-flip value is preserved, but its inferential interpretation was withdrawn. With additive counts and equal halves, squared rate error to the full record is exactly one quarter of error to the separate half. The package contains original inputs, source hashes, code, independent checks, numerical results, figures, and reproduction instructions. The study does not test clinical accuracy.

    Reused its 655 original source files, pinned source manifest, unmodified retrieval code, duration correction, and contact name matching. Wrote a new reference-design analysis and independent checks. This is the same patient source, not independent replication.
