[QUOTE="ilc, post: 1801316, member: 97996"] Ok, here you go. Just say you have a rifle that shoots an average of 1.0" groups with an SD of 0.3". Approximately 0.15% of groups will be less than 0.1", i.e. more than 3 x SD less than the mean. I'm not sure if you have a problem with the math or the language, so let's just say that Varmint Hunter's 16 year old group was a "statistical outlier". For the statistics nerds out there I realise that the distribution of group sizes may not be perfectly normal, but slightly skewed towards larger groups because of the lower bound of 0.0", but the principle of a small tail under 0.1" remains.
