How many arrows make a group? If it is three and you shoot 4 can you call one a flyer?

I don't see what the big deal is and why someone would laugh about tight groups. I put my arrows pretty close together myself and I know I don't shoot as much as alot of people. Just because someone isn't a pro doesn't mean they can't shoot like one. I don't shoot a great deal at 50, but when I do I can put 2 arrows nearly touching consistantly. With my new bow I have to be careful not the destroy my arrows inside of 40. Now that is fun. Good shooting everyone.
