+### ✅ Accuracy Highlights (based on benchmark tests)
+
+- Precision 10: < 3% average error up to 100,000 unique items
+- Precision 12: < 1.5% average error up to 100,000 items
+- Precision 14: < 0.7% average error at 100,000 cardinality
+
+### 🔁 Duplicate Safety
+
+Handles duplicate values correctly, estimating only **unique** cardinality. Example:
+- Input: 10,000 identical values
+- Estimated: ~10,000 (error: <1%)
+
