Understanding the Summary Data

High: This represents the highest velocity in the recorded string of shots.

Low: This represents the lowest velocity in the recorded string of shots.

E.S.: Extreme Spread - this is the difference in velocity between the highest velocity shot and the lowest velocity shot.

Ave: Average - this is the average velocity of the string of shots. This is the number to look at to compare whether velocity is increased overall, or decreased overall by a change in a variable.

S.D.: Standard Deviation - S.D. Is a mathematicall way of expressing how close most of the shots are to the average. The lower the Standard Deviation is, the more consistent the velocity is.

95%: This is an easier to understand way of expressing consistency. Statistically, there is a 95% chance than a given shot will vary this amount or less from the average.
