Body scanning runs the rollers up your back to estimate shoulder position and spine curvature, then maps the program to that estimate.

Why scans vary
Posture, clothing thickness and how far you sit back all change the result. If shoulder placement feels wrong, sit fully back and rescan; most chairs also allow manual shoulder adjustment.
