Ablation Study — Training Duration
We evaluated checkpoints at multiple steps to understand convergence:
| Training Steps | Success Rate |
|---|---|
| 2,000 | 2% |
| 6,000 | 17% |
| 10,000 | 31% |
| 20,000 | 36% |
Performance improves consistently but with diminishing returns, suggesting convergence begins around 10K steps on LIBERO-Spatial.
