I am not surprised by your findings.
When I use Archers Advantage to get speeds,Hoyt always comes out closer to the numbers than any other brand I have tried(at all draw lengths).They really seem to hit their speeds.(atleast the past few years)
Mathews has been notorious for exagerating their speeds,along with missing the draw lengths.
Sorry but I don't understand this.
I know the amo draw length is from the center of the valley(atleast that used to be the standard,not sure if it has changed) but it looks to me like if you have NO VALLEY,it should be measured from the wall.
I have an AM 35 on order and I actually ordered the black out with camo limbs and called and changed it to an all camo.Mainly,because the bow is strictly a hunting bow and I didn't want a slight glare to cost me the buck of a lifetime at some point.BUT,I love the black with camo limbs.If I were to get a target bow,that would be it.[8D]
