Lead wrist angle @ DAH

What it measures

Sportsbox’s public key-frame list uses seven codes (ADR, BCH, TOP, DCH, IMP, FCH, FIN—see their Key Swing Positions guide). “DAH” is not on that list, but many Swings-tab exports and coaches use DAH to mean the downswing checkpoint where the lead arm (forearm) is roughly parallel to the ground in the face-on 3D solve—the same delivery window this glossary previously called “arm parallel.” It is a different moment from DCH, where the club shaft is parallel to the ground (pair with Club–Hand Gap @ DCH). Match the exact label spelling in your session summary. There is no single universal “best” degree for every golfer/club pairing; prioritize repeatability at a locked camera before chasing a textbook midpoint.

Units: degrees

Why it matters

Relates to dynamic loft, shaft plane, and how you store or release lag before impact. Steady numbers here—low scatter on identical framing—usually matter more than parking on one exact degree borrowed from someone else.
