Well since I began shooting in July my groups shrunk considerably until about 3 weeks ago where I seemed to plateau and not improve much more. I read Byron Furguson's book and then read it again and last week, something happened, I started shooting "lights out" at 20 yards.I can't really explain it but when I look down the arrow, I have all the confidence in the world that the arrow is going where I want it. I don't mean to sound cocky, it's just kind of strange how it happened... I'm not complaining at all.
