Removing one of 85 people reduced the early-to-late Pearson correlation for exact nine-digit recall from 0.711 to 0.269 in ds003838 v1.0.6

We tested two scores for nine-digit recall in 85 people from OpenNeuro ds003838 v1.0.6. We compared early and late blocks in one visit. The Pearson correlations were 0.728 for correct positions and 0.711 for exact lists. Their difference was 0.017. Its 95% paired bootstrap interval was -0.156 to 0.627. This test did not establish a higher position-score correlation. Exact scores were zero in both parts for 39 people. Removing one person reduced the exact correlation to 0.269. The position correlation became 0.690. All 85 people remain in the primary test. The package includes source transcripts, new code, all planned checks, sampled indices, hashes, and figures. Separate verification and a fresh-source replay passed. These results describe behavior in one task and one visit.
