At a 0.8 correlation cutoff and a 1.25 size factor, later SEEG means passed shape but failed size in all eight sessions

An early five-pulse shape check selected 196 of 886 bipolar SEEG readouts in eight patient sessions. The source was OpenNeuro ds004696, version 1.0.1. The shape cutoff was 0.8. A later five-pulse mean passed size if its RMS ratio to the early mean was 0.8 to 1.25. Thirty-three selected readouts passed later shape but failed size. Every session had at least one such readout. The equal patient mean failure fraction was 14.1 percent, with a descriptive 95 percent interval of 8.9 to 21.8 percent. An early size check raised mean later joint agreement by 5.6 percentage points, but reduced retention and success yield. The package contains exact public-data products, all outcomes, source hashes, retrieval and analysis code, and figures. The result concerns recorded voltage in the same session. It does not establish neural amplitude drift or online BCI performance.
