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.
serve · elbow
right court sideRating 6/102026-08-02
Mistake: Racket elbow angle reached 152.6° at contact, which is over-extended compared to the recommended serve range of 60-120°.
Fix: Keep the racket elbow flexed closer to 90° throughout the serve motion.
Why it matters: Reaching with an over-extended arm on the serve reduces precision and touch, making shuttle trajectory inconsistent.
Drills
- Stationary serve practice maintaining a constant elbow angle near 90 degrees
- Low serve target drills focusing on compact forearm and wrist movement
clear · torso
right court sideRating 4/102026-08-02
Mistake: Shoulder-vs-hip rotation reached only 9.3° before contact (ideal is ≥20°), keeping the chest facing forward throughout the stroke.
Fix: Turn your chest away from the net during preparation so your back/shoulder faces the shuttle before unwinding.
Why it matters: Failing to coil the upper body removes core power from the stroke, forcing the arm to push the shuttle weakly.

- Shadow chest-rotation overhead prep drill
