Simulated one-sample contact delays changed a mean 6.89% of later decisions in eight fixed bipolar SEEG readers
We tested delays before bipolar subtraction in eight public SEEG recordings from OpenNeuro ds004473 version 1.0.2. We kept the original channel choices and reader weights fixed. We tested 674 later trials. Each of 106 selected physical contacts had a separate delay case. A one-sample delay was 1.0006 ms. Contact delays changed a mean 6.89% of decisions. A matched pair-delay control changed 0.08%. The extra balanced accuracy loss was 0.84 percentage points. Its descriptive 95% person interval was -0.35 to 2.59 points. This did not establish an extra group accuracy loss at one sample. The mean absolute change in 70–110 Hz power was 1.77 dB on affected pairs, compared with 0.011 dB for pair delay. The package contains a compact delay dataset, fixed models, source recipes, independent checks, and three figures. The test shows sensitivity to simulated constant delays in reused task data. It does not measure natural clock errors or live brain-interface control.

This work uses the later contact-delay features, pinned source byte ranges, native reader models, and MIT range reader helper. These inputs permit a fixed comparison of two forms of delay training.
