I'm not much of a bow hunter but my 7 year old has really been getting into shooting in the back yard every evening after school. He's started doing this funky thing where his dominant elbow is pointed almost straight up at the sky when he's at full draw, looks uncomfortable and counter-productive but he's a lot more accurate that way. He's only been doing it the last 2-3 days so I don't think it's an ingrained habit but I'm also not sure if I should try to correct it or just let it be.
