Short answer is it depends on what use the gun. Target shooting, competition shooting, prairie dog shooting you are looking for a gun that will hold tight over a long period of time with fairly rapid shooting. You don''t have time to cool off your barrel in the middle of a rapid fire string on the firing line.
Woods gun, going after deer or squirrel or that pesky long shot at the goat who refuses to let you get closer than 600 yards then be happy with a tight 3 shot group. You won't get a 4th shot at that kind of game and you won't be shooting so many shots that your gun will get hot enough to change point of impact.
That is why I go out with a clean barrel when I hit the woods. I sighted in my gun with a clean barrel. I cleaned the barrel and shot again the next day and cleaned it again, a week later did it again. If I get a good first shot with a clean barrel then a so called fouling shot is not necessary. 3 shot group is sufficient because if you haven't hit your quarry by then he will be out of sight anyway.
