Hitting input vs. Output still makes no sense to.me

[SevisonJN_PSN]

So SDS changes the analysis method on hitting. I still don't get it. My issue continues to be that a circle (not the ball or the bat) determines if a ball that is timed well is struck well. If the PCI isn't the ball (which it is not) and timed swings are good or better, what metric determines why a ball was popped up or grounded out for example? If we only get two data points when three are needed, how do we really analyze a result?

Ball is in the PCI and timed well. Now what determines the outcome, launch angle and exit velocity?
