MM,
We are one the same page as far as a machine rest goes. 10 shot groups will show human error, thats why we shoot them. Once you see it, you know you need to work on it.
The human error only matters if it's greater than the total variance in the gun & ammo; to determine that, you need a baseline.
Without the baseline to determine the gun/ammo variance & capability & just proceeding to start shooting ten shot groups, you really have no idea what is the gun/ammo & what is the shooter.
Obviously, small groups mean good gun, good ammo, good shooter.
Unless you are shooting matches that require 10 shot strings, or you're into self flagellation, it just really doesn't matter much.
