A little simple math give you the answer to your fishiness, newman.

Doing some back-figuring, D.Parsons is using a 436 gn arrow. Yours are 372 gns. Lighter arrows lose speed and energy at a much faster rate as they go downrange. At 60 yards, your 299 fps has dropped to 260 fps. Loss of 39 fps and 18 ft lbs of energy.

If you were to shoot a 436 gn arrow, your initial speed would drop to @ 286 fpsbut you'd wind up with an arrow doing something like 253 fps and carrying 62 ft lbs at 60 yards. A loss of only 23 fps and 12 ft lbs of energy. You'd have a trajectory very similar to what you've got now. It'd probably open your pin settings very slightly.
