I have a couple of questions.
1. Was this the Qubica speed measurement?
2. Was this on a strike ball, or a spare?
3. Were you using a strong ball, or plastic, or urethane?

The reason I'm asking all these questions is that qubica measures the speed a ways down the lane, after a hooking ball has made it's move. So a strike ball with a lot of hook can appear to be about 3 mpg slower than a plastic ball thrown straight.

one thing that works for me is relax your grip and follow thru...ala Pete Weber,..try and let the ball flow off your hand...I also shorten my first two steps (I take five) to slow my body speed down.

I seems to me as though you may be looking for tips on having a consistent swing.  I say this because you mentioned a difference in your ball speed.  Muscular tension is what makes the swing diferent from time to time.

I can't say that what helps me will help you, but, I think this ...- same back - same forward - ...feel the ball pause at the top of the back swing..., and just let it fall....  In order to change directions the ball has to decelerate and pause at the top of the back swing.  Look for the Feeling of the pause point. This will help you learn to allow the ball swing your arm, instead of you swinging the ball.  Let the swing be easy, as effortless as possible.  From the feeling of the free swing you can become very conscious of the ball and develop a very consistent delivery.

Good Luck and Good Bowling
