i say count them all. i include all flyers into my group sizing. i practice so that i can maintain peak performance with my handguns and to identify any areas of weakness. if i continue to have unexeptable 'flyers' with a certain gun in a certain scenario, that's what i will be practicing until i am comfortable with it. i don't shoot competition at all, so i'm not interested in averages. all my shooting is done in preparation of self defense or hunting, both of which depend alot on that first shot (which for me is usually the flyer).
