[QUOTE="Hawk in WY, post: 1460936, member: 70947"] It’s difficult to disagree with what the target is telling us, but whatI I don’t understand is why this method would work based on simple statistics. If the standard deviation of the original loads was 10 (20 might be a better average) the true velocity of each load would be plus/minus 20 to be 95% confident the velocities originally reported were within the true range and plus/minus 30 to be 99.7% confident. In other words, the differences we think we are seeing just might be due to chance. Shoot that ladder again and you are very likely to come to another conclusion. [/QUOTE]
