Shaft Angle @ DCH
Swing Analytics (Sportsbox-style positional metric).
What it measures
Face-on modeled shaft-plane angle when SportsBox stamps the shaft-horizontal DCH key frame (distinct from Shaft Plane @ ADR setup and Shaft Plane @ DAH when the lead arm is parallel). Coaches use steep versus shallow labels here—the same tripod lock as Shaft Plane @ ADR comparisons matters more than chasing tour snapshots.
Units: degrees
Why it matters
Planes the club on the way down while wrist lag and torso rotation evolve; pair Club–Hand Gap @ DCH and later DAH shaft rows for sequencing stories.
When the number looks wrong or noisy
Mis-tagging POS (reading DAH as DCH) gives opposite coaching conclusions—mirror exact SportsBox abbreviation on your spreadsheet.
