How to read these numbers

Body-axis inclination is the angle of the hip-to-shoulder line from vertical (an image-plane projection, so off-axis cameras read low). Angulation is leg lean minus torso lean (positive means the torso is more upright). Symmetry is the left/right peak ratio × 100. Rhythm variation is the coefficient of variation of turn duration (lower is steadier). Edge rate is the inclination change rate through the transition. Exact edge angle and foot pressure cannot be measured from video and belong to the sensor tier. Analysis is fully automatic with no manual correction — including the numbers that don't flatter.
