Five earlier 1 mA pulses gave mixed 2 mA SEEG forecast gains after two calibration pulses in three patients from 20 to 500 ms

We tested whether five earlier 1 mA pulses improve 2 mA SEEG voltage forecasts after two 2 mA calibration pulses. The fixed sample had three STReEF patients, 31 sites, and 54 ordered conditions. Coefficients came from the other two patients. The fourth and fifth 2 mA pulses tested forecasts from 20 to 500 ms. Person gains against tuned new-current shrinkage were 0.00%, +13.86%, and -1.34%. The mean was +4.17%. A fixed half-size new-current mean had higher mean skill against zero voltage: 30.67% versus 25.46% for transfer. Transfer had a mean gain of -4.32% against that fixed control. Thus, the test showed mixed benefit under the stated rule. The test pulses were reused from prior work. Current was linked to time and run. The result is exploratory and does not identify a causal current effect. Fresh retrieval of all 540 selected raw ranges reproduced every input array. The package preserves exact pulse products, all scores, source versions, range hashes, code, checks, four figure pairs, and repeat instructions.
