RE: bow speed?
03 hoyt magnatec cam 1/2
71# draw weight 29.5 DL gold tip 5575's cut at 27.5 inches (380 grains) 289.7 FPS
Same set up with the 5575's cut at 29 inches (392 grains) yields 285.5 FPS
Both setups produce 71 FT/LB of KE.
Thats with a D loop, kisser, super peep, Leeches, and through a wisker biscuit.
Not to shabby for a moderate priced bow.
I am picking up a 70# extreme vft this weekend. I will post chrony results after I get it home and test it.

300 Winchester Short Magnum, 150 grain ballistic Silvertip, 3300 fps.[:-]
Oooops, wrong forum.
Mathews Legacy, 29" draw, 495 grain arrow, 52# pull, 235 fps. Thats through a chronograph and is true speed. Folks that make bows always list IBO speed that is measured with a 30" arrow @ 70#. As you can tell, I shoot a shorter arrow at a more comfortable poundage (for me). Hunting weight is 62# but I've never chronographed that set up.
Tons of things affect speed. I could get another 100 fps out of my bow by going with straight fletching and an arrow half the weight. BUT, it would be very unstable in flight and sound like a rifle going off. In this months edition of Bow & Arrow a master whitetail hunter explains that most deer are taken under 25 yards. He recommends shooting a heavy arrow at a moderate speed because it's quieter, and the heavy arrow helps with the penetration.
Just my thoughts.

RE: bow speed?
For 3D: 325 grain arrow dynamics at 294 fps (ifaa rules dont allow speeds over 300) Its been done with a Mathews Rival pro at 29" draw - 62#
For hunting: I dont really know. I setup the bow for silence shooting alu's at 58#.
I guess its somewhere around 260 - 270
Bow is a Q2.
