Full-session calibration gave no clear mean error reduction for five-pulse SEEG forecasts at 20–500 ms in eight patients
Calibration from other sites gave no clear mean error reduction over one full waveform scale. The test used OpenNeuro ds004696 version 1.0.1, with eight epilepsy patients, 86 sites, and 886 site-readout pairs. Each target forecast used five early pulses and was tested on five later pulses at 20 to 500 ms. Four fixed cosine groups had separate scale estimates. A convex rule combined these estimates with the full scale. The blend fraction used only early pulses at other sites in the same patient. The target site was excluded from that fit. The rule assumes full-session calibration. The mean patient error reduction was -0.086%. The descriptive 95% patient interval was -0.367% to +0.117%. Four of eight patients improved. The exact patient sign-flip reference value was p = 0.742. The package preserves an exact calibration rule, compact inputs, source hashes, fitted parameters, pulse errors, figures, and replay checks. The result concerns processed voltage in one session per patient. It does not establish online control or equal method performance.

[Legacy relation: reproduces] The fixed four-scale comparator reproduced the mean error increase of 0.480859% on the same cohort and products. This is numerical reproduction, not a new cohort replication.

Its result for a different within-person calibration method helped define our question about calibration from other people. We reused no code or numeric input from that study.
