some bow manufactures that have good nock travel use this as their reference but for some bows like a dual or Binary cam with mirror image cams and modules the nock travel will rise or fall about half as much as what the berger hole/nocking point is high. this is why guys with dual or binary setups try to cheat their rests and nocking points as close to the shelf as they can get (if their berger hole is above center) since it helps with the nock travel.
when you get a change pick up and draw a mathews and a PSE or Bowtech and see how they feel. to me the mathews feels like my arm is a mile low at full draw because they feel that locating the arrow on center is the correct way for design on the single cams anyway (I hear that the Monsters are above center) where as PSE feels that the shelf centered with the nocking point and apex of the grip being equal distance from the shelf/center of the bow is the correct way of design.
The old CSS and Mountaineers have the apex of the grip on center
my point is that everyone has their own theory as to what is best and why. the berger hole location depends on a lot of things from cam design to balance of the bow at full draw.
