A time correction increased mean agreement of later STE and MNI starts within 5 ms in 18 SEEG sleep records
We tested a time correction for released HFO detector starts. We used all 18 SEEG records in OpenNeuro ds005398 version 1.1.3. One offset per patient was chosen with early marks, then held constant for later marks. Counts stayed fixed. At 5 ms tolerance, the mean STE match fraction rose from 14.02% to 21.42%. The paired mean gain was 7.41 percentage points. The 95% patient bootstrap interval was 4.45 to 10.62 points. Fifteen patients gained; two lost; one had no change. The 2 ms and source-score checks had intervals that included zero. This result applies to released sleep marks. It does not establish neural event accuracy or clinical benefit. The package contains all source inputs, code, results, checks and repeat instructions.

This package supplied the pinned source manifest, compressed source inputs and retrieval code. All 94 inputs were checked against fresh source requests. The present correction analysis and independent checks are new.

The signed start-delay result in the same 18 SEEG records motivated a new early-to-later test of time correction. It did not test correction on later marks.
