Patrick, from any tees, aren't 8, 9, and 10 the hardest three par 4s on the course, and isn't 14 the hardest par 5?
Anecdotally, my scoring average from the ~6850 yard set of tees reflects what Mark observed. I'm even par or slightly better than that for the first six and slightly over par if you include seven, which I've made a complete hash of a couple of times. I'm +6 per round or so on the next seven holes, with most of the damages coming at 9, 10, and 14. And I'm somewhere between +1 and +2 per round for the closing stretch.
Part of the difference is length, but an even bigger factor, I think, is what happens once you get out of position. In the opening stretch, you typically can recover. In the middle stretch, except for 13, if you end up in the wrong place, you're toast unless you take your bitter medicine.
