Want to know your velocity? Good news! You do not need an expensive radar gun! Read on..
There is a website developed by some Florida Grad students that is a very accurate velocity predictor.
Go to http://faculty.tcc.fl.edu/scma/carrj/Java/baseball4.html
The simulator on the website estimates the distance a ball travels based on "X" velocity off a bat. But it also works for arm/pitching speed.
Here's what you do. On the website,
1) Change the elevation to your area's number. Mine is 2000 feet above sea level, so I type in 2000 and click "change".
2) Set the optimum angle to 36 degrees. (Optimum angle is a range of about 32-40 so 36 is about right.)
3)Change the speed to however fast you think you are and click "hit". The simulator will then give you a distance number. For example, based on my elevation of 2000, 78.8 MPH = 267 feet.
4)Go to a football field, warmup, then throw for maximum distance. Note the distance, then using the simulator, you can monkey the velocity number until it matches the distance you threw. That's how fast you are!
It really, really works. My son threw 78.8 in October, then went to a college camp in January and was clocked on the Stalker at 79 MPH.
There is another website out there that says something like, if you throw 300 feet you throw 90 MPH. Don't believe it. The website above yields a much lower (but way more accurate) number.
Everyone try it and give some feedback. But remember, tell us if the predicted velocity matches a Stalker or Jugs. (Not Bushnell. I have one and it's not very accurate.)
