A2A Measurement for 08 Cheetah

[Thrawn30]

Do you measure the A2A from center line of axle to center line of axle or from the farthest part of your limb to the other. The reason why I ask is when I measure Centerline of A2A I get 30" on my Cheetah and when I measure from the farthest point of my limb to my other limb I get 30.5". The bow spec is 30.5” A2A and I want to make sure I'm measuring in the right place.

I measure from the mid of the upper axle to the mid of the lower. But it is the way I measure it and i am not sure if i am doing it right. :P
