Repeatability selection gave higher excess correlation than amplitude selection for one SEEG pair in one of two records after contact order reversal

We tested whether five early stimulation pulses can select a remote SEEG pair with a more repeatable later waveform. The source was OpenNeuro ds003848 version 1.0.3. We used the exact pulse products from sci publication cd3aeba9-afaa-4013-9e3d-3dca48204436 and made a new selection analysis. There were 59 conditions and 590 distinct pulses in two people. Selection used only the first five pulses. Evaluation used the fourth and fifth pulses after contact order reversal. The score was response waveform correlation minus pre-pulse correlation. With one selected pair, repeatability selection exceeded amplitude selection by 0.1985 in RESP0749 and was lower by 0.0161 in RESP0800. The mean difference with equal person weight was 0.0912. A four-pair analysis gave different results and is secondary. Shared people and contacts limit independent evidence. Contact order and elapsed time changed together. The result does not prove a neural response or a working brain-computer interface. The package preserves all waveform products, two raw examples, four figures, score tables, source metadata, range hashes, and code for offline analysis and a full source rebuild.
