How proficiency is calculated
Score 0–100 from technique (30%), athletic base / footwork-knee-hip (20%), court craft / recovery-position (15%), clean form ≥7 (10%), low severity ≤4 (10%), shot repertoire breadth + weakest shot (10%), and consistency (5%). Official ranks need ≥3 clips analyzed or ≥2 sessions; thinner samples stay Provisional.

Mistake: Shoulder-vs-hip rotation was only 5.4 degrees during the backswing and hit.
Fix: Turn chest sideways during preparation and rotate fully through contact.
Why it matters: Lack of torso coil prevents kinetic energy transfer from the hips and core, leaving the stroke reliant on arm strength.
Drills
- Shadow clear practice focusing on turning chest to side-on and unwinding to front-facing
- Partner toss drill practicing side-on posture and full chest rotation
