Five calibration pulses gave mean later signed template AUC of 0.939 compared with 0.859 for one pulse in eight SEEG sessions
We tested the pulse cost of selecting a recording pair and fitting a mean response template. We used public SEEG data from eight patients, 86 stimulation sites, and 886 candidate pairs. Each rule used one to five early pulses and the same five later test pulses. Mean later after-versus-before AUC was 0.859 with one pulse and 0.939 with five pulses. The exact patient sign-flip test gave p = 0.09375. It did not establish a gain at the 0.05 level. Separate descriptive contrasts gave about 0.050 AUC for pair selection and 0.030 for template averaging. Five pulses changed the selected pair at 46 of 86 sites. The package preserves exact products, source waveform checks, score tables, fitted templates, and an offline monitor. This reused cohort tests pulse-aligned response separation. It does not prove a neural effect or a live BCI benefit.
