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

  1. Shadow front-court lunge repetitions
  2. 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

  1. 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

  1. Upright wall shadow serves focusing on keeping the chest high
  2. Mirror low-serve posture holds to lock in upright spinal alignment
