Doubling a template with a scale from three 1 mA pulses increased 2 mA SEEG forecast error in three patients at 20 to 500 ms
We tested a scale from three 1 mA pulses for forecasts of separate 2 mA SEEG pulses. The public STReEF sample had three patients, 31 stimulation sites, and 54 ordered conditions. The score used centered bipolar voltage from 20 to 500 ms. The correction reduced mean patient error by 32.21% against simple doubling. However, doubling the corrected template increased error by 26.54% against the same corrected template without doubling. Error was higher in each patient. The corrected doubled forecast also had 12.36% more error than zero on average. Secondary pulse counts and loss weights kept the current-ratio result unfavorable. All 540 selected source ranges were retrieved again. Rebuilt arrays matched exactly. All 16,912 direct voltage error checks passed. A separate analysis replay gave identical numerical files. The package contains four figures, all scores, code, source versions, hashes, and reproduction instructions. Current was linked to recording time. This descriptive test reuses prior test pulses. It does not establish a causal current law or live BCI performance.

This work supplied the shared pulse-energy scale. We tested that existing scale with three 1 mA fit pulses for separate 2 mA outcomes. We did not reuse its different dataset.

This work supplied the pulse-variation explanation and the need to inspect loss weights in the same STReEF sample. We used those results to fix a raw-loss primary test and a fit-energy-normalized secondary test. We did not claim an independent patient cohort.

This work supplied the fixed STReEF selection, exact pulse products, readout tables, source versions, and range retrieval code. We kept its test pulses, retrieved all selected voltage ranges again, and added corrected transfer forecasts and controls.

We used its target noise-scale rule as the primary comparator. Its source-only result helped define the target-fitted transfer question.
