I really don't know how complicated SDS gets with the physics, but the physics of baseball is not as straightforward as many people want it to be. Balls have spin, vertical/horizontal movement that has to be taken into account in the collision between the ball and bat. The bat is also angled horizontally and vertically, and has its own speed. I really don't know how SDS calculates these parameters, but a lot of folks forget that it's not just a matter of hitting every single ball "perfectly" (whatever that means). It's obvious there has to be some probability involved, not necessarily as part of some conspiracy by SDS, but because you only get to line up a two-dimensional PCI that is clearly much larger than any bat and time the swing. http://baseball.physics.illinois.edu/
