Strike rotation °

Use this line with cohort percentiles or coach bands in Sportsbox when available.

Aim (simple): No single optimal degree fits every golfer—camera pitch skews readings. Loose aim: stabilize within roughly ±4–8° versus YOUR baseline on identical framing or push cohort percentiles upward week over week.

Typical ranges: Mobility/club dictate absolute °—trend against your own repeatable captures before chasing leaderboard averages.

Camera setup affects inches and degrees—track your own trend more than someone else’s raw number.

What it measures

SportsBox Chest Turn at the IMP (Impact) key frame—the rotation of the chest segment around the vertical axis versus address in the face-on 3D solve: (−) closed to target, (+) open. Only compare numbers from spreadsheets or Swing rows stamped “IMP,” not pooled generic Chest Turn @[POS] without a phase.

Units: degrees

Why it matters

Captures torso orientation at the strike window—the moment-of-truth read coaches pair with sway, lift, side bend, and pelvis mates for flight and low-point stories.

When the number looks wrong or noisy

Blurry glove contrast or tripod drift widens IMP scatter silently—reject suspect frames.
