If a fellow is honest about the groups he shoots, he has to acknowledge there is a difference between “demonstrating” a particular group size and actually averaging a particular group size.
If one says he fired 10 ten shot groups at 100 yards under good conditions and gave me the statistical average, I may well agree that is a decent representation of average group size.
But, if that same fella picked the best couple of groups out of the ten, ten shot groups fired, one may well ask if that was a “demonstration” of how it actually shot by showing the best it could shoot on occasion but not as an average?
This post is making no point other than to be realistic about what the rifle can actually do by shooting it enough for the statistical tabulation of its accuracy to be valid, and avoiding cherry picking our groups.
Not saying anyone here is necessarily doing that, but it is all too common in the forums I frequent.
