2 weeks ago, bowling terrible, my track was high, very close to the fingers and thumb. I realized then that I wasn't coming around the ball. After seeing my coach, I now come around the ball, but my track is moving away from my fingers and thumb. I am putting more on it, and once again bowling decent.
Why is it moving, due to my release? Also, why does it move, and whats the difference between low, medium, and high track?
