What is backspin on a driver or iron, and when is spin too high or too low?
In plain language, what does "Back Spin" mean on my monitor or export?
Back spin is the rotation of the ball around a horizontal axis perpendicular to the flight direction. It creates lift and affects trajectory and stopping power.
Units: rpm
Why does this metric matter for ball flight, dispersion, or scoring?
Back spin controls trajectory height and how much the ball stops on the green. Too little: ball runs out, hard to hold greens. Too much: ballooning, loss of distance, wind vulnerability.
What is a typical or competitive range for this stat?
Driver: 2,000-3,000 rpm. 7-iron: 6,000-7,500 rpm. Wedges: 8,000-10,000+ rpm.
What usually makes this number look bad or noisy in real rounds?
Excess back spin: steep attack, high dynamic loft, or thin contact. Low back spin: shallow path, delofted face, or fat contact.
