 ## Performance Profile
 
+### Operation Count (Streaming Mode)
+
+Classic Pivot Points compute PP and 6 support/resistance levels from previous bar HLC — O(1).
+
+| Operation | Count | Cost (cycles) | Subtotal |
+| :--- | :---: | :---: | :---: |
+| Store prev HLC | 3 | 1 cy | ~3 cy |
+| PP = (H + L + C) / 3 | 1 | 2 cy | ~2 cy |
+| R1 = 2*PP - L | 1 | 2 cy | ~2 cy |
+| S1 = 2*PP - H | 1 | 2 cy | ~2 cy |
+| R2 = PP + (H - L) | 1 | 2 cy | ~2 cy |
+| S2 = PP - (H - L) | 1 | 2 cy | ~2 cy |
+| R3/S3 extensions | 2 | 2 cy | ~4 cy |
+| NaN guard + state update | 1 | 2 cy | ~2 cy |
+| **Total** | **O(1)** | — | **~19 cy** |
+
+Cheapest O(1) pivot variant — pure previous-bar arithmetic, no smoothing, no buffers beyond a 1-bar state.
+
 ### Implementation Design
 
 Pure arithmetic with no loops, no buffers, no auxiliary data structures. Each `Update` call performs 3 divisions (via the single division in PP), 6 multiplications/additions, and 3 comparisons for NaN validation.
