Understanding Key Data: Smash Factor vs. Attack Angle

Smash Factor is ball speed divided by club speed. A higher number (near 1.50 for drivers) indicates efficient energy transfer. 

Attack Angle is the vertical direction the clubhead is traveling at impact (positive is hitting up, negative is hitting down). 

Serious players target a positive attack angle with the driver to optimize launch conditions and maximize distance. Use these metrics to dial in your gear and swing path.
