Jens, I think you meant 1/3 AHEAD and 2/3 BEHIND the focusing distance. It's easy to verify this. Look at the DOF scale on a lens (you'll probably need an old lens to check this) and you'll see that the far-side limit of DOF encompasses more metres, feet or furlongs (as is your wont) between itself and the focusing mark, than falls between the near-side limit of DOF and the focusing mark.
