1 · Executive Summary
This is Kaya's third VALD session — Feb baseline → May full battery → this 16 Jun re-test (folded in from her ACL-readiness screen). Across 4.5 months her power trajectory keeps trending the right way, while the work has narrowed to one clear theme.
Encouraging:
CMJ jump height is at an all-time high — 26.7 cm (25.9 → 26.0 → 26.7), still climbing while bodyweight held steady. Well above the 14U female norm (~22 cm).
Take-off symmetry markedly improved — 15.9% → 10.9%, back to her February level and almost inside the <10% target. The bilateral push is evening out.
Arm-swing jump up to 28.4 cm (ABCMJ), and the arm-swing contribution grew (CMJ→ABCMJ gap 1.1 → 1.7 cm) — she's using her arms better.
The clear #1 priority — the single-leg / landing gap:
Single-leg jump height continues to decline — 17.0 → 15.0 → 12.7 cm — even as her two-footed numbers rise. Her bilateral power is masking a real and widening unilateral gap.
Landing-force asymmetry remains elevated at ~23% (well outside the <10% safe zone) — unchanged from May.
This matches her ACL screen the same day (Monitor flag, single-leg + landing the drivers). It is the same story from two angles, which makes it the unambiguous training focus.
Bottom line: Kaya keeps getting more powerful, and her bilateral symmetry is improving — real wins. The next block should go almost entirely at single-leg strength/power and landing mechanics, where the gap is now the one thing holding her back. Note: this session didn't repeat the Squat Jump, so the SSC (CMJ vs SJ) check should be re-run next time.

3 · CMJ Bilateral Trends
One line per metric, one dot per session, oldest on the left. Net % is baseline → current. Higher is better except contraction time.
4 · Bilateral Asymmetry
% asymmetry between left and right legs. Shaded green band is the <10% safe zone. Lower is better.
5 · Single-Leg Trends
Best-trial single-leg jump. The widening gap vs her rising bilateral numbers is the headline of this re-test.
