The guy isn't using anything complex either, Doug. It's basic geometry. What he's doing is nothing more than simple physics. The math would be the same that any software is programmed to calculate. It's basically a situation where in both his spreadsheet and the ballparks' software, y=mx+b. If y=distance, we can solve the equation by knowing m and b.
The problem isn't with that guy's formulas or the software's formulas. They are calculating the same things... because again, it's geometry. The issue is that he admits he has to make some "best guesses" when it comes to the ball coming off the bat, estimating the speed based on how long it took the ball to land, etc. Because he has to guess on a few of these things, the calculations can be incorrect. Same with the guys at the ballpark. They have to estimate on their inputs, which can leave room for error.
I assure you, Doug, they're using basically the same concepts. It's simple geometry. It's just a matter of human error when guessing the inputs to make the calculations.
