I understand the concept, but the definition states "as many as desired". I have also been to many matches and depending on the angle, lighting, and condition of the target it is hard for my old eyes to see holes. I even went to the .40 over the 9mm for bigger holes. If someone shoots, looks at his gun expecting it to be empty, then shoots again at the same target to get to slide lock, then you have something. If someone hoses until empty, they are shooting "as many as desired".
