Thorax vs hip speed (Swing Analytics): What It Is & Why It Matters
In plain language, what does "Thorax vs hip speed" mean on my monitor or export?
Ratio of maximum chest rotational speed to maximum pelvis rotational speed in the downswing—often discussed as stretch-and-recoil or “X-factor” style sequencing.
Units: ratio
Why does this metric matter for ball flight, dispersion, or scoring?
Summarizes how much the torso accelerates relative to the hips; links to kinematic sequence coaching.
What is a typical or competitive range for this stat?
Population references (~1.5 men, ~1.4 women driver in some datasets) are guidelines only.
What usually makes this number look bad or noisy in real rounds?
Low pelvis speed with decent hands: sequencing work; low torso speed: mobility or bracing limits.
