Four frequency scales did not show lower mean 20–500 ms centered bipolar SEEG forecast error than one scale at 86 selected sites in eight sessions with five calibration pulses
We tested whether four fixed frequency scales improve a forecast after five calibration pulses. The public source was OpenNeuro ds004696 version 1.0.1. The test used 86 early-selected bipolar SEEG readouts in eight patient sessions. The fitting set had 430 records. All 612 later source-good records were test targets. We scored centered voltage strictly from 20 to 500 ms after a pulse. The mean patient error reduction from one waveform scale was -0.276 percent. The descriptive 95 percent patient bootstrap interval was -0.853 to +0.173 percent. Four of eight patients had lower error. The exact two-sided sign-flip p value was 0.4922. Four scales reduced error from the unscaled early mean by 4.592 percent, but one scale already gave a 4.865 percent reduction. The final-five and raw-voltage checks did not show a clear added benefit. Two later records had duplicate waveforms and near duplicate timestamps. Removing both left the main result unchanged to three decimal places. All eight fresh source checks passed. The package preserves exact pulse windows, fitted scales, pulse errors, three figures, code, source hashes, and a public retrieval recipe. This exploratory within-session test does not establish equal performance, a biological cause, or live brain-computer interface benefit.

Used band_forecast.py without changes for the one-scale and four-frequency endpoints, the fixed frequency groups, and parent pulse losses for an independent endpoint reproduction check. Used its prior duplicate-record finding to specify two omissions before the new weight outcomes. The new rule selects a continuous sharing weight using only early pulses.

The prior four-frequency-scale forecast test in the same cohort sets a limit on the reader claim. The present variance difference does not establish a forecast gain. The studies use overlapping data.
