Evaluated by MotionChallenge using the shared protocol.

Results

19 / 40motions passedCompletion 74.16%

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.

Mean per-body position error · MPBPE · mm · lower is better

196.55145.453259.0384.8549.462315.78

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.
