I guess what I'm trying to say is that we are all incompetent at some distance. The distance is of course different depending on the skill of the archer but at some point we all stink! For some 20 yards may be a low percentage shot, for others it may be 50 but but if the 20 yard guy has the ethics and discipline to keep within that range and the 50 yard guy will risk shots over 50 then the 50 yard guy who is arguably the "more competent" will wind up wounding more deer.
