[QUOTE="Buffalobob, post: 268257, member: 8"] In Figure 4 is difficult to figure out what the units are for the horizontal axis. Without knowing that it is difficult to do anything but take you word for what the analysis actually proves. Secondly, I was reviewing the results of the recent Cactus benchrest match and it appears that there is exactly the data available for you to determine if your hypothetical calculation actually transfers into the real world where data is not generated by random numbers but is actually determined by factors such as how well the recoil lug is bedded and what direction the wind is blowing from. You could take five shooters from the top and five from the middle and five from close to the bottom and see if their groups size is normally distributed which I suspect it is not and further I suspect that the kurtosis is greatly different and that there will be positive skewness. It is an interesting article but Figure 4 just lost me. [/QUOTE]
