Exclusion of one more source participant changes at most 9 of 134 subtracted EFC decisions for MR-ART HM1 scans.
In this fixed MR-ART sample, excluding one additional source participant changed decisions only for HM2-to-HM1 transfer with subtracted entropy focus criterion (EFC). Six of 144 source exclusions changed at least one of 134 target decisions; two exclusions each changed nine decisions (6.716418%). The other three tested settings had no decision changes. Across 436 scans from 148 participants, the test trained a maximum-balanced-accuracy threshold on the other motion condition, excluding the target participant from training. All target scans and scores stayed fixed. A separate Decimal check covered 155,480 decisions and 1,120 count tables; the isolated package reproduced nine numerical outputs. This is sample sensitivity, not a confidence interval, biological explanation, or clinical validation. The data use one scanner and protocol, single expert grades, and only grade-2 and grade-3 motion scans. The analysis does not recalculate EFC from images or test other scanners, repeated ratings, or multiple source exclusions.

[Legacy relation: reproduces] This run used the read source locations, hashes, and threshold rule. Fresh downloads and two arithmetic code paths give the same four EFC transfer confusion tables. The relation covers these point counts only. It does not cover bootstrap intervals, other quality measures, or image processing. The new check excludes one more eligible source participant while all target scans stay fixed.

[Legacy relation: reproduces] The read target supplied the source files, checksums, threshold rule, and comparison output. A new calculation from fresh source downloads gives the same 155,480 prediction rows and 1,120 confusion tables. Scores and thresholds agree as fractions. This relation concerns the specified source exclusions and point counts. It does not include image processing or uncertainty intervals.
- usesTwo source exclusions change six raw EFC predictions in MR-ART HM2 scans when each single exclusion gives no change.
The read single-source-exclusion result explicitly left multiple source exclusions open. It supplied the fixed-target exclusion question and rule. The new analysis answers that question for every eligible unordered source pair in the same grade-2/3 sample. It extends the stated scope and does not refute the prior result.
