The numbers look a little better now. But it still seems odd. Only 1" off the DL, and 6 grains over the IBO arrow weight. Then a d-loop and WB, and it only shoots 314. Hmmmm, my guess is Mathews fibs on numbers. Because their is no way that bow loses that much speed from what I have formentioned.
DL alone bumps it down around 330. Few more from arrow weight. How long of a Dloop? Thatll shed a few. WB also will shed a few. 330 to 314 is a 16 fps discrepancy. 16 from a slightly heavier arrow, dloop, and WB....believable to me.
Plus, these bows are unique. Not EVERY SINGLE bow will hit exactly 340 IBO out of the box with no exceptions. This is why some companies like BT went to a range instead of a set number....to keep all the speed freaks from griping about a speed being off by a few fps from IBO....Speed can be had from tweaking the tune of the bowas well.
With alot of bows, it just depends. One can excede IBO while the next one down the line be 3-5 fps below IBO. While they are performance machines...there is still some variance within them.
