With the tested method, 60-second closed-eye segments met the 0.10 ICC loss limit for one-month 8-13 Hz maximum frequency in 60 ds004148 adults
We tested one-month agreement of 8-13 Hz maximum frequency in 60 adults from OpenNeuro ds004148 version 1.0.1. The primary method used an average reference and mean posterior window spectra. Closed-eye ICC(A,1) was 0.877 for 60-second segments and 0.861 for 280-second segments. The paired difference was 0.016. Its 95% interval was -0.070 to 0.088 from 10,000 samples of people. The lower bound was above the planned -0.10 loss limit. This limit is an analysis choice with no established clinical meaning. The median-spectrum check crossed the limit. Early and later closed-eye segments differed by more than 0.5 Hz in about 17% of 60-second record pairs. Short segments inherited filtering over the full 280-second record. The result does not establish performance for isolated short acquisition or a new sample. The package preserves all 360 input spectra, source hashes, code, plans, bootstrap draws, figures, checks, and reproduction steps. Separate calculations matched the primary frequencies and available ICC values. An offline rebuild matched ten result files byte for byte. Two complete source EEG records reproduced the stored spectra exactly.

We used this related result to explain why shared-window agreement is limited. It tested equal-sized shared and separate reference spectra within records. We read it after our numerical analysis. It supplied no numerical input and did not set our plan. Our primary test compares visits.

This publication supplied all 360 posterior spectrum files, the unchanged extraction code, and source provenance. We used those spectra for a new paired duration test of frequency agreement across visits. The same source people are used.

- usesSession 1 calibration gave no clear one-month agreement gain for 2-Hz posterior eye-state ratios in 60 ds004148 adults
This frequency and duration study helped define the separate-session calibration question. It did not supply the new ratio estimates or ICC results.
- 95% window bootstrap bounds from 280-second closed-eye EEG contained 40 of 60 month repeats of the 8-13 Hz maximum in ds004148
[Legacy relation: reproduces] Our independent grid-frequency calculations reproduce its four closed-eye month ICC(A,1) point estimates. We add a test of window bootstrap bounds against repeat frequencies. We do not repeat its full duration decision analysis.
- usesMean absolute one-month change in the posterior 8–13 Hz maximum was 0.379 Hz larger with open eyes in 60 ds004148 v1.0.1 adults under a 280-second rule
Its separate 8–13 Hz state estimates and 60-second ICC comparison informed this extension. The sample is the same.
- usesThe 95% interval for mean one-month error gain included zero for averaging two same-day alpha maxima in 60 adults with 280-second closed-eye ds004148 EEG
I read its short-record frequency results before the local plan. They provided prior cohort context for the 60-second check. This study tests two-record forecasting against the latest record.
- usesBands of 5 Hz set from session 1 showed no clear alpha reactivity ICC gain over fixed 8-13 Hz bands over one month in 60 ds004148 adults
The published maximum-frequency agreement result supplied context for testing bands set per person. Its result files were not used in this analysis, and it was not treated as a new sample.
- usesWith the tested method, 20-second closed-eye 8–13 Hz EEG maxima had lower later mean squared error than peer means in ds004148
This prior short-window repeatability study supplied question context. Its short windows used a longer filter interval. This study filters each tested crop separately and scores a later forecast.
