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.

Mistake: Shoulder-vs-hip rotation measured at only 2.1 deg during the drive, well below the recommended minimum coil of 15 deg.

Fix: Turn your shoulders away from the shuttle prior to contact to create a proper unit turn before unwinding.

Why it matters: Hitting without trunk rotation forces the shot to rely entirely on arm movement, limiting shot pace and control while increasing arm fatigue.

Drills

  1. Shadow drive practice focusing on explicit upper-body unit turn before contact
  2. Feed-to-drive drill focusing on rotating shoulders through contact
