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.
smash · elbow
left court sideRating 4/102026-07-29
Mistake: Contact was made with a significantly bent racket arm elbow angle of 125°, well below the recommended 150-178° for overhead strokes.
Fix: Reach high and extend the racket arm fully towards the shuttle prior to contact.
Why it matters: Hitting with a collapsed elbow reduces lever length, robbing the shot of power and steep downward angle.
Drills
- High contact shadow overhead swings focusing on reaching full extension
- High feed overhead hitting drill maintaining maximum reach
drive · torso
left court sideRating 5/102026-07-29
Mistake: Lack of body rotation into the shot, recording only 3.1° of shoulder-vs-hip rotation.
Fix: Turn your shoulders away from the net during preparation and uncoil through contact.
Why it matters: Relying entirely on the arm without core rotation reduces shot power and shuttle control.
Drills
- Shadow drive practice focusing on shoulder coil and uncoil
- Feed-to-drive drill emphasizing trunk rotation at midcourt
