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.
clear · elbow
centre court sideRating 4/102026-07-29
Mistake: Right racket elbow was severely bent at 77.5° during contact instead of fully extending between 150° and 178°.
Fix: Reach up high and extend the right arm fully to strike the shuttle at maximum height.
Why it matters: Hitting with a bent elbow drops the contact point significantly lower, sacrificing power, steepness, and court coverage.
Drills
- High contact shadow swings focusing on full arm reach overhead
- Fixed feeder overhead clear drill emphasizing hitting at peak reach
clear · torso
centre court sideRating 4/102026-07-29
Mistake: Minimal torso rotation during the overhead stroke, achieving only 4.2° shoulder-vs-hip rotation compared to the ideal minimum of 20°.
Fix: Rotate your non-racket shoulder toward the net during setup, then initiate the swing by driving your back hip and chest forward.
Why it matters: Without proper kinetic chain rotation from the core, power generation relies almost entirely on arm pushing, drastically reducing shuttle speed and court depth.
Drills
- Shadow overhead clear with exaggerated unit turn and trunk rotation
- Half-court feeder clears focusing on chest-to-net rotation before contact
drive · torso
right court sideRating 6/102026-07-29
Mistake: Shoulder-vs-hip rotation reached only 4.7° during the drive stroke, well below the recommended minimum of 15°.
Fix: Rotate your chest away from the net during preparation to load core rotation before driving through contact.
Why it matters: Insufficient trunk rotation deprives the shot of core power, forcing upper-arm push and reducing shot velocity and depth.
Drills
- Shadow coiling drives: Practice rotating hips and torso back prior to executing forehand drive strokes.
- Feeder drive rotation drill: Have a partner feed flat shuttles while focusing on turning the chest away before hitting.
