bat speed

Dd was measured at 115. She swings a LXT 34" -9.

They weren't using a zep, it was some type of radar. ex division one coach/player was doing the testing. Not sure that matters but just figured they weren't using some cheap pocket radar.

The important thing is to compare apples to apples and it sounds like in that group your daughter was outstanding.
When I talked to NFCA at Pennsbury last year, they said their measurements of ball exit speed were very accurate and they were using new equipment and this would be their standard after talking to coaches around the country about what they wanted to see. Ball exit speed is higher than swing speed of course and I looked at their results and very few hit over 70 out of thousands of high school girls across the country during their testing.

Zepp Labs had a booth or something at PGF 12U Nationals and was tweeting speeds that sounded exceedingly high. 85 mph from an 11 yo and 88 from a 13 yo.

Outliers (the results and not the hitters). Did they really calibrate the Zepp for every hitter? I would doubt it.

This is why we have sample size in statistics.

Come on that's it. I was hoping for more then that. I do have to say that measuring bat speeds & exit speeds are alright, but I have seen some really ugly swings with high exit speeds. The exit speed doesn't matter much if you can't hit a ball with consistent. Google Sports Skill Measurement & improvement. Place my dd use to train at started this with exit speeds my dd when she was 11yo hit an exit speed of 61.2.

She could always tryout for DFP's team but that's pushing it

Are speeds usually checked hitting off the tee, front toss, or live pitching?

Ball exit speeds at NFCA are off a tee, close to a net with a radar behind it. One school did it with front toss but the speed of the incoming ball will affect the exit speed so you are adding another variable.

How about using zepp checking swing speed? Tee, front toss, or live pitching?

The speeds were reported by Zepp to promote their product. Whether outliers or from a miscalibrated device the numbers seem unrealistic.
