I had a friend just buy a new '07 Bowtech Tribute. It is a 29" draw. The birth certificate indicated that it is IBO'ed @ 302fps. Bowtech's website indicated that it should see 320-328fps. I know, or thought, Bowtech measures their speed with the nocks and hush kits on the string already and I don't think that a 1" draw length would reduce the speed by 18-26fps. I looked at other Tributes and the highest birth certificate speed I saw was 304fps.

I am not knocking Bowtech as I own one. My Old Glory's birth certificate is 306fps with the same draw length and I know the Tribute is supposed to be a much faster bow.

Does anyone have any insight to this? Not a huge deal, more curious than anything.
