    Default Spin Axis Tilt - Amount of Curvature

    Are there any guidelines for the amount of curvature of a ball (ex. 10 yards, 20 yards, etc.) when comparing ball speed and spin axis? For example, if a ball speed is 150 and the spin axis is -3*, how far will the ball curve?

    I'm looking for general principles and understand there are a lot of moving parts (ex. spin rate, launch angle). Maybe I could ask the question a different way. At what spin axis degrees does one start seeing unplayable misses?

    A spin axis tilt of 1* will result in a 0.7% curvature offline at a given distance.....

    Does the amount of spin/ball speed have anything to do with that .7%?

    As far as I do understand what Trackman is saying that spin axis tilt within 2 degree will not influence the ball trajectory.

    but also found this old thread : http://www.brianmanzella.com/golfing...curvature.html
