a good way to figure out lateral pitch is through flexibility of ones thumb. if you are right handed, right lateral will get you out of the ball sooner. have someone else (you can't do it yourself) pull your thumb across to your pinky finger. if you can easily reach it, usually means 1/4 or 1/8 lateral to the left because they have a more flexible thumb. obviously vise versa if you cant reach it. Generally, short and stocky people with thicker and smaller hands cannot reach it and have right lateral to help them get out of the ball sooner.
