Chest Turn @ IMP
What it measures
SportsBox Chest Turn at the IMP (Impact) key frame—face-on rotation of the chest versus address at the strike instant: (−) closed to target, (+) open. In current SportsBox builds the on-screen guide for this row is typically a narrow band near ~19–21° (club and cohort overlays can nudge it). Log the value from the row explicitly labeled IMP; do not substitute Chest Turn @ TOP or unpooled “Chest Turn” without a phase tag.
Units: degrees
