It might give you an idea of where your son is at metric wise by doing some independent testing and then getting some verified metrics from Perfect Game (PG) or Prep Baseball Report (PBR). Lots of thoughts here on the board (use the search feature above) on PBR vs PG and how they do or don't measure exit velo or tee velo or if the 60 times are laser or hand timed.
I am guessing that there will be some sort of metrics taken at whatever showcase or camp you attend. Parts of those metrics matter a lot to some schools and none of it matters to many others. Once you have those metrics from PBR/PG or another way you can do some comparing to current 2023 commits to target schools or kids in your area or even the 2 D1 kids your hitting coach works with.
