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.
kill · footwork (to the shuttle)
right court sideRating 5/102026-07-29
Mistake: Approached the net shuttle with an upright stance rather than a deliberate front-foot lunge.
Fix: Lunge dynamically forward on your right foot to establish a stable hitting base at the net.
Why it matters: Lacking a solid lunge base prevents proper weight transfer into the shot and limits reaching height at the net.
Drills
- Shadow front-court lunge repetitions
- Multi-shuttle net push and kill lunge drill
net · knee / lunge
right court sideRating 4/102026-07-29
Mistake: Extremely shallow knee bend of 29.2° during the forehand net movement (ideal range 85-120°).
Fix: Sink down onto a flexed lead leg with a knee angle near 90° while keeping your chest raised.
Why it matters: Failing to lower the center of gravity through a proper knee lunge forces the torso to bend excessively (87.4°), ruining balance and racket control.
Drills
- Shadow net lunges focusing on bending the front knee to 90 degrees while keeping an upright posture
serve · torso
right court sideRating 5/102026-07-29
Mistake: Excessive torso lean of 81.5 degrees relative to vertical during the serve (ideal is 0-15 degrees).
Fix: Keep your torso upright with a slight forward angle under 15 degrees throughout the serving motion.
Why it matters: Bending forward excessively disrupts posture stability and alters the contact window, making height control over the net inconsistent.
Drills
- Upright wall shadow serves focusing on keeping the chest high
- Mirror low-serve posture holds to lock in upright spinal alignment
