The wave (accommodation-breaker): week 1 jump with 25s, week 2 30s, week 3 35s, then restart at 25 — each load keeps its own height record, so every week hands you a fresh number to beat instead of grinding the same one. Order in a session: ① 2 fresh DB jumps at the wave load (max height, tracked) → ② tracked unloaded verticals (3–6, chase the raw PR, 30–60s between) → ③ squat → ④ 1–2 contrast DB jumps riding the potentiation. Full countermovement always, never seated. Beat the record or land within 92–95%; if heights fall backwards, the dose is over. Stiffness family (Super Cat pogos · calf-ankle jumps <0.15s contact · banded jumps) stays in tiny snap-only doses.

Taper week — DON'T drop to lighter dumbbells. Cut the number of jumps, never the load. Reducing intensity in a taper makes you fresh but detrains the exact quality you're about to test. And the wave already handles it for you: 3-week wave inside a 4-week cycle means wk1 = 25 · wk2 = 30 · wk3 (Sharpen) = 35 · wk4 (Taper) restarts at 25 — your lightest, fastest wave load lands on test week automatically, at the smallest dose (2 jumps instead of 4–6). The ultra-light end is already covered by the tracked bodyweight verticals every lift day — lighter than any dumbbell, purest velocity, own record. Adding 10/15 lb loads would only split your jump data across five records and slow every one of them down. Only recalibrate the whole wave down (to 20/25/30) if a 25 lb jump ever drops noticeably below your BW jump height — that's a permanent load correction, not a taper adjustment.
