Having been throwing on my driveway into a net for as long as I can remember, and recently starting to gun myself a good amount of times that I do (albeit with a JUGS and not a Stalker), I highly doubt that there is that much difference. I throw lowish 80's (82-83) on the driveway, and I feel like were I a sophmore touching 90 or near it, I would know about it
. I infact have been gunned off the mound in a game earlier this year (about end of march, dont rememer exact day) and it was only 2-3MPH higher at the most (85).Just curious as to what leads you to believe in a 5-10MPH difference.
