Swing Analytics (Sportsbox-style positional metric).
What it measures
Peak modeled rotational shaft velocity (degrees per second)—Player Plus kinematic stream, distinct from positional shaft-angle rows @ ADR/DCH/DAH.
Units: degrees per second
Why it matters
Anchors kinematic sequencing with torso/pelvis deg/sec peaks and linear club mph summaries.
When the number looks wrong or noisy
Marker jitter creates synthetic spikes—triple-run clean captures.
