Karthik Sen vs Kavya Joshi

Wed 11 Jun · 47 min · Coach Priya Sharma · Fixed camera · Pose + rally intelligence · No wearables

Executive coach brief

Karthik is an aggressive finisher who wins when net pressure and first-three-rally tempo hold. Today’s primary limiter is not power — it is backhand rear-court reset under fatigue (minutes 20–30). Fix that, and his profile already supports U-17 elite singles load.

What the camera sees — biomechanics & profile

Each panel below maps directly to pose analysis from your fixed court feed. We measure player movement and load — not shuttle trajectory or racket-head speed.

Karthik profile — reach and coverage overlay

Player profile · compounding

Session #14 · same file every week

Reach utilisation 84% — Karthik uses most of his wingspan on stretch retrieves, but backhand clears still sit 6% short of forehand depth. That matches the heatmap cold zone.

19 net approaches today (+5 vs last session). Aggressive profile is intact; the issue is return-to-centre after deep BH, not willingness to attack.

Methodology (what this report is built on) — Fixed court camera · overnight processing · Gemini rally layer (rallies, shot tendency, finisher/grinder, point endings) · pose layer (coverage, distance, peak player movement, fatigue drift, biomech flags). We do not measure shuttle speed, racket speed, or doubles re-ID in this sample. Profile data compounds session-over-session from the same player file.
