Actually Mo, if you add 10 fps for every inch of draw length you're missing to get to the specs listed in the original post, you start out with 265 at 25.5", so you'd have 275 at 26.5", 285 at 27.5", 295 at 28.5" and 305 at 29.5"... Now add the extra 70 grains he's shooting over you, and you're both about the same... in fact, his isn't bad at all.

Take the 1/2" draw length off of jquillin's specs, and that cuts 5 fps off IBO specs. Add the 50 grains he's shooting above IBO specs, and that robs another 17 fps... that's a total of 22 fps. Add that back onto the 298, and jquillin's bow would be hitting 320.
