Pretty useless without more info.
I can only speak for the rounds I shoot, but my 308 and 30-06 loads are still delivering 150- 200 ft/lbs more energy than listed @ 500 yards when using 180 gr bullets.
Even with a 200 yard zero my flattest shooting loads with 130gr/308 and 150gr/30-06 loads, both at a quite hot 3050 fps don't shoot as flat as the data listed. He must be using a 300+ yard zero and some pretty light loads for this comparison.
But to be fair, the overall rankings don't look too far off if you were to select the best load for each chambering. There might be a few that would move up or down the rankings slightly if the "best" loads for each are chosen.
