Greg,
You need to draw a bare shaft to full draw, i.e. where your drawing forearm is in line with your arrow. At that point someone needs to put a mark on the arrow opposite your nose, indicating where the fletching should start. For me, it was about 1 3/4" from the valley of the nock. Later, I found this to be a little short, because I want the cock feather to barely touch my nose at full draw, so I increased it to 1 7/8".
The danger of a method where you hold at full draw is that you will "settle in" and lose back tension. Clearly, Rick doesn't do that, or he wouldn't be able to shoot as well as he does. I've watched him shoot and he anchors in two separate movements: the first to reach full draw and the second to move his nose behind the cock feather. He does move his head a little bit to get his nose behind the cock feather, but I don't think his string hand comes forward any.
