KA covered it well.

One thing I would add- Minor deviations from "spec" are normal (e.g your 1/8" deviation in A2A length- limbs always have a little variance) and frankly don't concern me. What concerns me is if the brace height is correct AND the cam/cams are in the proper rotational position- I dont mean just synched together but also timed correctly (single cams still need to be timed, but have nothing to be synched with)

As for particulars on allowable manufacturers tolerance, I'd defer to my former colleagues (and the new additions, congrats guys!) on the BT Corp. Staff, of which there are a bunch on these forums. I am not familar AT ALL with the Binary cams or the BowTech line from 2005 and later.

FWIW- this is one reason I really came to prefer single cam systems. Just get the cam timed properly, and it's easy to keep track of, and you rarely need more than a twist or two put in the cable if you have a decently made string/harness. Easy peasy minimal maintenance.
