[QUOTE="Mike6158, post: 338870, member: 1039"] One other thing to remember about statistical data- the number of samples is very important. 5 - 10 samples isn't really enough to calculate an accurate standard deviation reading (SD). The chrony will do it for 2 rounds but it's not a usable number. ES is a similar but different issue (easier to calculate) but I think I would rather shoot 50 and throw out the highest and lowest reading than shoot 10 and call it good. There are so many variables in reloading that it makes ES a tool but not THE tool. I agree that the target tells a better tale for ES than the chrony. [/QUOTE]
