Chest Side Bend @ IMP
Swing Analytics (Sportsbox-style positional metric).
What it measures
SportsBox Chest Side Bend @ IMP—upper-spine lateral tilt in the modeled frame at Impact. Distinct from Chest Side Bend @ ADR/TOP exports and generic multi-phase Chest Side Bend rows missing explicit IMP tags.
Units: degrees
Why it matters
Explains torso incline beside the strike—stack with Rotation + Lift + Thrust IMP for complete posture-of-impact.
When the number looks wrong or noisy
Using DAH or DCH side bend values while labeling them IMP destroys coaching deltas—enforce POS spelling.
