What is the margin of error on the device that is measuring the EV.......?We finally got to a store with a Hit Trax and hit a few bats. Exit Velocity:
Ghost Advanced 32 drop 11 -- 54 mph
Demarini 2020 CF -- 32 drop 10 -- 54 mph
Demarini Prism -- 32 drop 10 -- 53 mph
LS 2020 LXT -- 32 drop 10 -- 52 mph
Ghost Advanced 32 drop 9 -- 52 mph
LS 2018 LXT -- 31 drop 11 -- 51 mph (HER CURRENT BAT)
Sad thing is, we were there specifically to try the Ghost Advanced 32 drop 10. And they didn't have it. Even after I called in the day before and they said they did.
So, I'm thinking the Ghost Advanced 32 drop 10 is the way to go. Based on the data above, can anyone weigh in on that? Makes sense, yes? For what it's worth, it was her favorite.

i dont know about hit trax. but the Blast motion sensor is within .5mph of the pocket radar ball coach
Found something:
Mike Donfrancesco, the founder of HitTrax had this to say about our data logs:
“The data captured by the HitTrax System provides a quantitative and objective measurements of a players’ performance. Reports showing incoming pitch speed and outgoing exit velocity have an accuracy of +/- 1 mph RMS. "
Point being the numbers @uncdrew gave are pretty much a wash imo (which isn't surprising given the magnitude of the exit velocity and how bats are designed) ..pick the bat the kid is most comfortable with...

There's certainly a lot to be said about getting the one that is her favorite. No doubt they need to have confidence in the bat they are using. But if you go Advanced 32/22, she will be going up at least 2 oz's based on the bat weight database. That's a fairly large jump.LS 2018 LXT -- 31 drop 11 -- 51 mph (HER CURRENT BAT)

Having weighed now close to 20, 32/21 GA's and not a single one coming in under 23 ounces (drop 9). The few 32/22 that I weighed were roughly around 23.5 ounces. So talking .3-.6 ounce difference in the drop 11 and drop 10 at the 32 length. I would wait until they have one to test and then compare the two. I think key might be if the drop 10 feels more balanced than the drop 11 at virtually the same weight then go drop 10. Just realize the CF was at least an ounce lighter despite one thinking it was an ounce heavier if weights were accurate.
