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: Your racket elbow was over-extended to 140.3° at contact, far past the ideal 60-120° range for a low serve.
Fix: Keep your racket arm elbow comfortably bent and close to your body, guiding the shuttle with gentle thumb pushing action.
Why it matters: Extending the elbow too straight reduces touch and control, causing the shuttle to pop up high over the net and invite an immediate attack.
Drills
- Shadow backhand low serve drills maintaining a constant soft elbow angle
- Target serving to the service line focusing purely on thumb flick action with a stable elbow
clear · torso
centre court sideRating 6/102026-08-02
Mistake: Insufficient shoulder-vs-hip rotation of 13.9° at preparation (ideal is 20° or more).
Fix: Turn side-on with your non-racket shoulder pointing toward the net before uncoiling into contact.
Why it matters: Failing to coil the torso forces the shot to rely purely on arm effort, drastically reducing stroke depth and speed.
Drills
- Shadow clear repetition focusing on starting side-on and rotating hips into the shot
- Feed-and-clear court drill enforcing full shoulder turn before stroke initiation
