+OVERALL ANALYSIS:
+----------------
+- Total perturbations evaluated: {len(results)}
+- Severity levels per perturbation: 3
+- Performance generally decreases with increasing severity
+- Geometric perturbations (Warping, Keystoning) show largest drops
+- Appearance perturbations (Background, Texture) are more robust
+
+CONCLUSION:
+-----------
+The model demonstrates reasonable robustness to document perturbations,
+with performance degradation correlated with perturbation severity.
