Training may have been the wrong word and yes I am just speculating on what data this tech could provide. But these are not crazy parameters we are trying to measure. Say if you know your baseline, you could try little things to make tweaks to say the spin or initial velocity. I want more spin so I cock my wrist more. If it shows improvement, try to duplicate, if not, move on. That kind of stuff. I am not talking about anything drastic. If I throw 400, I shouldn't expect 500 just from a few tweaks. But the ability to see the data for the throws you are making means you can attempt to change that data in a specific way. And there is proof in ball golf that the ability to measure and see that data immediately can lead to big improvement over time b/c you can see you are going in the right direction as opposed to just guessing based on where the ball ended up, or in our case disc.
That might not be unreasonable early on.
