Roll Speed (Putting)

• Definition
  • The speed at the point where the ball starts to roll (when peripheral speed and velocity are equal).
• The Use of Roll Speed
  • Roll Speed is useful to look at in relation to Ball Speed and Speed Drop, as this is a measure of the Ball Speed after the initial Skid Phase.
  • Therefore, Roll Speed should be assessed in relation to Ball Speed, to get a better assessment of how much speed the ball loses during the Skid Phase.
