a lot of folks think cam position supercedes a bow fitting you, but that's incorrect - as a matter of fact its one of the most incorrect archery myths out there.
I will third, fourth and fifth that!
Way too many people worry too much about the technical stuff and not enough about just plain trying to shoot better.
If you are shooting 5 inch groups at 20 yards chances are it is not because your cam is a sixteenth of an inch out of rotation. It's probably because your draw length is too long, you are pulling too much weight and your grip is wrong and or not consistent. Among a dozen other things we could name.
