Re: best method for measuring a 3 shot group
The added zero would be more common because everything is measured in thousands of an inch (the third place after the decimal)
However it's been long enough since you've shot bench rest that you've forgot how to read ha ha . A .99 inch group is only 10 thousands of an inch away from an inch and won't win any competitions at all. A .099 inch group is outstanding and that is what I'm assuming you meant to type. You're just missing where he's putting the decimal (and you placed it incorrectly in your other example). Mathematically he's 100 percent correct.
I don't mean to start a fight or sound like a jerk, he could add the zero because it is more common, but he does not need to. And again... you missed a decimal place or maybe even two by saying that a .99 inch group was a screamer. .099 would be a screamer and .009 is basically one hole and I have no idea how they can measure a tear in paper to that kind of precision and accuracy.
