PhysDiff Table 1 reports on HumanML3D (mm): MDM Penetrate 11.291, Float 18.876, Skate 1.406, Phys-Err 31.572; PhysDiff w/ MDM 0.998, 2.601, 0.512, 4.111; MotionDiffuse 20.278, 6.450, 3.925, 30.652 (rows sum correctly; no mocap ground-truth row). GMD reports MDM foot-skating ratio 0.284 and 0.161-0.309 across variants in trajectory-conditioned tests. Scores come from authors' own runs on different protocols, so they show direction (physics projection reduces artefacts) not a portable threshold. HumanML3D is 20 fps, so a clip's frame rate matters for any per-frame threshold.

Curator qualifications: Table 1 ('Text-to-motion results on HumanML3D'): MDM Penetrate 11.291, Float 18.876, Skate 1.406, Phys-Err 31.572; MotionDiffuse 20.278, 6.450, 3.925, 30.652; PhysDiff w/ MD 0.898, 1.368, 0.423, 2.690 (row not in the candidate); PhysDiff w/ MDM 0.998, 2.601, 0.512, 4.111. All candidate values match the source PDF bytes; completes C3R-0139 (item hold lifted without a new download). GMD and Yi et al. tables still not re-read. Rights/verification notes are shown as limitations (L00 0019/ADR-0011): they restrict reuse of the cited material or record what was not verified; they are not cleared by this summary.

Limitations: [rights_conflict_record] Dataset distribution/training terms (AMASS policy) preserved as rights conflict.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
