A weight from other patients did not lower observed late SEEG power forecast error in 20 patients
We tested whether a weight fitted in other patients could improve a late high gamma power forecast after brain stimulation. Public OpenNeuro ds006519 data supplied 34 records from 20 patients. Each test patient was excluded from fitting. Mean absolute error was 1.133 dB with the fitted weight and 1.122 dB with a fixed half correction. Benefit over the half correction was -0.0118 dB. Its descriptive 95 percent patient bootstrap interval was -0.0776 to 0.0149 dB. All weights were fitted again within each draw. Fitting gave no observed average gain. This reused cohort does not establish equivalence or new-patient performance. All 35 raw source records passed fresh hash and spectrum checks. A separate process reproduced all 14 numerical files. The package includes code, compact spectra, source recipes, predictions, draws, checks, and three figures. The scope is offline power forecasting, not intention decoding or safe stimulation timing.

We first read its other-patient forecast report after the primary scores. Its shared pre reference led to the added reference check. It did not set the primary plan. The two studies use different windows, bands, targets, losses, and weights.
