The handanchoris different for fingers thanfor a release.That puts the elbow in a different position as well as the head.
They also are showing a locked elbow which in most opinions isn't a good fit for a compound.
In no way would these guys be able to maintain that form in a kneeling or twisted position.The form they utilize is one that is extremely stretched out which is good for what they do but isn't going to work well from a deer stand or in the 3-d woods.
There are a couple things in there that I think cross the spectrum,front shoulder load and height is one.I didn't read all of it but it does look like they also prefer shoulder width feet.They are showing an open stance which I personally am not a fan of but some people do like it.It does help create clearance.I feel that is a personall thing.They do point out posture and I agree with the even weighted posture,some disagree.
Kind of like different forms of martial arts.
