 Well, what PitchLogic does, and I quickly mentioned it, it's got a circuit board inside with a number of different sensors, and it breaks down your total spin to side spin, back spin, rifle spin, or spiral spin, and it gives you what the ball did while it was in the air. So it's not so much a predictor of what your body's doing, although we do have your extension numbers and a variety of things. And little leaguers can use it to show where their arm slot is,
