If you are aware of a mistake, the 'called flier', you don't include that shot in the group measurement.

If you make a mistake that you aren't aware of, then how do you label a shot a mistake if you are not aware of it being a mistake? Logic says you can't. You have to include it because it might not be a mistake. It might be an accurate reflection of the gun/ammo.

The only 'mistakes' that count are the ones you know are mistakes, and they should be excluded from the measurement.

How many samples do you have to take?
