Across 16 simulated tasks, the authors report 83.4% average success, 23.9 percentage points above the strongest evaluated baseline. On three real-world tasks, it beat action-only and auxiliary-geometry methods by 50.0 and 21.2 points. The gains come from the reported task suite and do not establish general dexterity.",
