Measuring Ball Spin

A successful bowler will create a certain amount of spin on the ball as they deliver it, and this spin interacts with the land conditions to create a specific path along the lane to the pins. It is useful to be able to calculate the amount of ball spin.

It is easy to determine the amount of ball spin (revolutions) you obtain after your release. You need to place a piece of white tape above your finger holes on the ball. Then roll your normal shot down the lane. There are two methods to count the number of revolutions, the second is more accurate.
