Wayne- I think I can help you with this- spent a couple days with Rick this summer at a course he gave here in Ontario. Great guy! And he helped me considerably.
Rick seeks for three anchor points- the feather on the nose, the first thumb knuckle on the bottom of the earlobe, and your first finger gripped around the string just under your cheek bone. [This assumes 3 under, of course.]
Here's a couple pics showing the three anchors. [Note that I am gripping the string with 4 fingers, only because I do not have my glove on.]
One other thing that needs to be considered is that to accomodate the feather on the nose, you will likely need to refletch your feathers further down the shaft in order to properly set this anchor. When I came home from my course, I set about stripping the fletching from all of my arrows, in order to refletch them in the new position. Here's a shot of one of them.
I naturally achored in what some would call this 'high' position, and shot 3 under- so this came easily to me. If you are shooting split, and lower- then it will be more of and adjustment. But this position feels very comfortable, allows one to better feel the back muscles, and also [generally] allows for a slightly longer draw. So you might even have to change the length of your arrow to properly set up for his approach.
The other main point that he makes is to 'trust your bow arm'. Again, this took some effort to put my 'trust' in where I was concentrating, and to not 'aim'- but it sure worked. My accuracy definitely improved.
