The 95% interval included zero for extra early-to-late disagreement of non-target Pz means with equal letter weights in 17 selected ERP CORE records

We tested early and late non-target Pz means in public ERP CORE data. The score used 300 to before 600 ms and equal physical-letter weights. Fixed response, EEG, and count rules retained 17 of 40 people and 1,994 trials. The mean squared temporal difference was 3.643 microvolts squared. The exact expectation for balanced random halves of the same pools was 4.371. Mean extra disagreement was -0.728 microvolts squared. Its 95% person bootstrap interval was -3.494 to 2.224 and included zero. This test did not resolve positive extra disagreement. A planned within-block check gave 5.158, with an unadjusted interval of 1.203 to 9.370. That check used different pools, weights, and time gaps. All seven planned checks are reported. The exact reference conditions on recorded trials and does not assume independent EEG trials. The bootstrap assumes independent people in this selected sample. The package preserves all 8,000 Pz epochs, full trial tables, source versions and hashes, split membership, bootstrap draws, code, and instructions. Independent checks matched all eight comparisons. Fresh retrieval of all 40 raw records reproduced 160 extraction files exactly. A full numerical repeat passed. The results do not establish score equivalence, a neural cause, or reliability across visits.
