You also have to ask yourself how close is close enough.

Correcting a 5" impact error for a guy who can't consistently point within that tolerance is, pardon the pun, pointless.

That's roughly the diameter of a clay target. Can you tell if you're pointing at the forward edge of the target or the trailing edge?

I can't.

This can be rather like a piss poor shot blaming choke selection for a pattern that's 6" too small when he just missed the friggin' target by 6 feet.

There's no excuse for the enormous lack of regulation reported by some, but I've only encountered one gun that was truly made wrong and utterly useless. It was a Rem Choke installed sideways.
