Constant convex common reference mixtures of mean19, Fz, Cz, and Pz gave 10 Hz sample wPLI more than 0.01 above each vertex score in 22.3% of 10,560 ds004504 v1.0.9 cases
The test used all 88 processed EEG records in OpenNeuro ds004504 version 1.0.9. At 10 Hz, it tested 120 pairs per record. Constant convex mixtures of mean19, Fz, Cz, and Pz gave a sample wPLI increase above 0.01 over the greatest vertex score in 22.35% of 10,560 person-pair cases. The mean increase was 0.0082, with a 95% person bootstrap interval from 0.0073 to 0.0093. A proof and two linear programs give sharp ordinary sample wPLI bounds when the denominator is positive. The code checks attaining weights, direct signal scores, and numerical dual bounds. The package includes data, source hashes, retrieval and analysis code, all results, and independent checks. Each pair has its own attaining reference. The maxima do not form one network under a shared reference. The findings concern observed scalp scores in this reference family. They do not show a disease effect.

This work supplied the complete Fourier input, source manifest, retrieval code, and single-pair bound code. We used them to test one common reference across three pairs.

The preserved solver fitted constant reference weights to maximize ordinary sample wPLI on each fit block. The new test scored those weights on separate time samples.
