Well, there is no such thing as one recipie for every barrel. You shoot, you clean, you shoot, you clean until there is no copper fouling, and then move to 3 shots, clean, 3 shots clean until no copper, and then move to 5 or 6 shots. By that time you might decide fouling you recieve is fine. Some move to 10 shots at that point.

No set rules for every barrel. Some barrels I have had had no fouling from the start, some remington's fouled every shot, and you couldn't break it in.
