Guys, you're over thinking again. Specs are just close approximations of what the company has found to work the best. Close is close in most cases. A2A can vary 1/8" as can brace height. Cam orientation is another matter. If the cam is over rotated on many bows it causes excess vibration and it's resultant noise.
Get the specs close then make sure the cam orientation is close. If you have 1/2" of cam groove showing that's fine. If you need a little more then twist the string some. 9/16" isn't going to hurt. Let the other specs fall where they may.
Tune the bow and enjoy shooting it. In time the strings are going to creep a bit and it'll change the specs anyway. Just relax and try to have some fun.
