How is the rev rate computed?  It is often sited but never explained.

Time how long it takes for the ball to go from the foul line to the head pin.  Then count the number of times the ball revolves going down the lane.  From that, you can compute the number of revolutions per minute, or RPM, of the ball.

I believe the rev rate is revolutions per minute.  So if Chris Barne's rev rate is 425, his ball would make 425 revolutions in a minute.  The computers used measure how many turns the ball makes during a certain area of the lane, say arrows to head pin.  Time how long the ball takes to cover that area, and how many revolutions (turns on its axis) the ball makes over said area.  once we know the data, simple math takes over.

Just take the number of rev's the ball made over the area, divide by the total amount of seconds the ball took to travel the area...that gives you revs per second.  Take the revs per second, multiply by 60 (60 seconds in a minute), then you get your rev rate.
