Sometimes they might get warmup pitches, but usually it is just in game pitches. It does take an operator to control everything. Not that anyone's asking, but it is very costly.
I do know that this TM data is very important to MLB clubs. They pay TM a lot to have access to the data compiled at PG events. Next year, that model will include college programs, but only the biggest programs will be able to afford it.
I think everyone in baseball is starting to understand the importance of all this new technology. No doubt it is helping some players that previously might have been overlooked. We have learned a lot with our partnerships with TrackMan, Zepp, and others. Years ago we used the standard numbers associated with the 5 tools. Now we sometimes have 10 times those numbers to look at. We now understand spin rates and how certain spin rates create results. Why the slower velocity guy might be harder to hit than the higher velocity guy. We used to rely on eyesight to evaluate things like movement of pitches and speed of the bat. Now there is equipment that does it more accurately.
