So say you want to know player X's average ball strike point behind the baseline over the years, to illustrate how he has developed a more aggressive approach - easy enough. Or the time of average baseline to baseline shot, or the average height over the net, or pretty much anything you can imagine. Literally any time the ball is in play, there's a computerised 3D model of it.
The accuracy of the system is such it seems they can even calculate what they can't directly measure, for example spin rates - the physics are all well known, and spin is essentially excess deviation from a normal predicted trajectory.
Yea I'm sure they used this Hawkeye technology to gather those info in the SAP analysis, the question is whether this data was available to users only for the San Jose website or there's a way to have the same data for other tourneys
