I still dont buy that a 10000 psi difference between GI and commercial only offers a 100-150 fps gain. I think it would be more along the lines of something like 550 fps, which isnt what you see with the numbers given.
I think the link above sums thing up about as close as we're going to get, without someone actually doing some comparison testing on all, all on the same equipment.
