One reference number from the glossary—not a target for every golfer.

Benchmark band

Match mobility

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 dictates band—younger/smaller arcs can pattern effectively with narrower stretch if sequencing is tidy.

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

What it measures

SportsBox-style X-Factor at TOP: torso–pelvis rotational separation measured in degrees at the same TOP key-frame—conceptually Chest Turn minus Pelvis Turn per SportsBox nomenclature. It is angular stretch at setup of transition, NOT the Downswing Core speed gain factor (which compares peak rotational speeds later). NEVER mix this metric with sway gap inches or speed ratios logged elsewhere.

Units: degrees

Why it matters

Single-number summary of coil stretch; coaches pair with Chest/Pelvis Sway/Lift stacks and Mid-Hands traces at TOP for quality control.

When the number looks wrong or noisy

Camera roll or asymmetric clothing contrast can perturb segment locks enough to widen scatter—trust repeated clean captures.
