As far as I can tell, here are Brian's best posts in laymen's terms describing how to perform the release.
Post #725: My personal experiment with the new release is going well. #1 thing to watch>>>>>>Don't TUG the left arm in transition.
Post #759: All I do is feel like I get the clubhead and arms started early without tugging, and bend my left wrist through impact as back-on-itself as I can. Definitely a freewheeling thing.
Post #764: Actually, the beginning of the rotation around the coupling point will probably happen sooner than the low point of the coupling point. And, it may FEEL LIKE it happens right away.
Post #857: If you don't turn enough away from the ball, you have NO CHANCE of not tugging. This is about limiting your pivot TO and THROUGH the ball, not in the backswing
Post #1266: From the top of your swing, try to start the arms before the unwind, and feel a little "out-toss" in your wrists. Have your hands go wide to the right as you continue down, and when you start feeling some out-force in the clubhead, start rotating the club head forward around the middle point of the hands in the direction of the right wrist straightening. This will put even more "out-force" energy in the club head. At that point feel like you jump off the ground and pull inward on the grip to strike the ball. Post impact, bend your left wrist back all the way without rotating your left arm much.
