Raw Test Data
Velocity comparison between 1bps and
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
20 shot target strings fired at 1bps,
Freak Barrel - All American Tip - 0.687"
Peak sound levels in dB, measured at
a distance of 10 feet from the muzzle, approximately 45 degrees from the
axis of firing.
