 **Data Integrity & Occlusion Handling:**
 - **Visible joints:** Direct depth measurement from TrueDepth sensor (<3mm accuracy)
-- **Self-occluded joints:** Estimated via scaled MediaPipe world landmarks anchored to visible wrist position (~5-8mm accuracy)
+- **Self-occluded joints:** Estimated via scaled MediaPipe world landmarks anchored to visible wrist position (5mm accuracy)
 - **Euler angles:** Unwrapped for continuous visualization without ±180° discontinuities
 - **Confidence scores:** Each joint has a confidence value (1.0 = depth-based, 0.7 = estimated)
