Mean MNI minus STE HFO start delay was positive for every largest 20 ms match set in the first hour of 17 of 18 SEEG sleep records
We tested whether pair choice could reverse mean delay between released HFO detector starts. We used the first hour of 18 public SEEG sleep records from OpenNeuro ds005398 version 1.1.3. Each pair used one STE and one MNI mark on the same channel, at most 20 ms apart. We first found the largest pair count. We then found exact delay bounds over every match set with that count. There were 7,414 pairs on 535 channels. Every largest match set gave a positive patient mean MNI minus STE delay in 17 records. One record gave a negative mean. Exact equal patient mean bounds were 4.143453 to 4.159561 ms. At 50 ms, the cohort bounds widened to 2.994276 to 5.027058 ms. Two patient bounds then included zero. We supply the bound proof, event membership labels, complete bound match sets, source bytes, retrieval pins, code, and repeat instructions. All 94 fresh public source checks passed. Arbitrary matching enumeration and a separate assignment solver agreed for every source candidate part in all six settings. Fresh-input and offline repeats matched all 13 numerical files by size and hash. This is a new measurement analysis of a reused cohort. It measures released detector marks, not true neural onset or signal travel time. It does not establish a correction for every channel or clinical benefit.

This earlier shared marked time study informed the onset matching question and the 20 ms rule. The current study calculates signed delay bounds and event membership on the reused cohort.

- usesEarly channel corrections reduced mean later detector timing error across 18 SEEG sleep records at a 20 ms match limit
We reused the exact source archive, pinned manifest, decimal time parser, matching implementation, and matching proof. The reported channel delay variation informed the early calibration question. This study adds later prediction scores on the same cohort.

- usesChannel delays fitted in the first 30 minutes increased mean 5 ms detector agreement in the next 30 minutes over patient delays in 18 SEEG sleep records
This study uses its archived source objects, source manifest, retrieval code, and adapted parser checks. Its full-hour delay evidence informed the question. This study adds an earlier-fit, later-test comparison and does not claim an independent cohort replication.
- usesA time correction increased mean agreement of later STE and MNI starts within 5 ms in 18 SEEG sleep records
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.
