I think more in terms of "useful" patterns, and my examples are purely involving hunting chokes. or lack of it. It's OK to grind up clays at 23 yards with a tight choke, but that fat rooster pheasant or ruffed grouse is going to be destroyed if you center it, and you can't always ride them out, especially grouse. No head games with a wide-open choke in that situation, just shoot.
