Success and completion use the first declared failure. MPBPE measures position errors over the benchmark’s declared body origins, with three alignments over two time ranges.

69.1464.761620.2143.1640.881404.16

Entire-motion errors include every frame through the endpoint, including post-failure states. The other range ends at the first failing sample, including that sample.
