The three MR-ART motion rank probabilities keep the same order after each removal of one or two participants.
This study tests whether the order of three image-quality rank probabilities in the MR-ART dataset changes after removing any one or two participants. It partially reproduces four of 40 endpoint-metric records from an earlier publication: all 51 compared numeric fields agree exactly, including four main records and three bootstrap differences. Across 8,000 eligible scan pairs, rank probabilities were 0.851000 for total signal-to-noise ratio, 0.826750 for the coefficient of joint variation, and 0.714375 for the entropy focus criterion. All 148 single-participant and 10,878 two-participant removals kept this order. The full-sample 95% bootstrap interval for the total-SNR minus CJV difference includes zero, so the removal results do not establish a higher population rank probability for total SNR. Results apply only to the fixed tables, grades, metric directions, and pair rules; they do not exclude effects from larger removals or changed ratings.

[Legacy relation: reproduces] The target gives the source paths, checksums, main endpoint, metric directions, participant order, seed, bootstrap rules, and expected records. The new program gives the same four main metric records and three differences from shared bootstrap draws. This is a partial reproduction of four of 40 endpoint-metric records. The new analysis also calculates every removal of one or two participants for that endpoint.

Its participant-removal tests keep expert grades fixed. I used that tested scope to choose the new grade-change question. Its reported SNR-minus-CJV interval limits the population interpretation; this run does not repeat its removal or bootstrap calculation.
