Axle-to-axle question for Mathews Conquest Triumph

According to the Mathews website my bow is supposed to be 39" axle-to-axle. In reality how close should this be? Should it be bang on to within a really small fraction of an inch or is within 1/4" good enough?

Treat it as a guide but don't expect it to be exact. Some makers say 39 inchs 'on average'
I've done a couple of bows lately. When I fitted strings and cables exactly the length on the label, the AtA and the brace height were close to what was in the spec.
Change the cam, the draw weight and length there will be variations and 1/4 isn't a problem.
If you need to alter the draw length you can change the start rotation of the cam, this in turn may affect brace and AtA. If you need to synch the cams, tightening a cable will have one effect and loosening the other may have the opposite effect. Same if you twist the string to get the peep rotation correct.
Twist the string up you will find AtA decreases and brace height increases, the opposite if you untwist it.
In conclusion, roughly set the spec as published, (assuming it is) and then be willing to find it changing as you complete the set up.
If a change you wish to make would make the bow further from spec, consider whether you could make a different change to keep it in spec and still achieve your result.
(eg, would twisting both cables work better than untwisting the string.?)

It's a single cam bow so no timing and only one cable ;)

But it doesn't really matter, it's certainly not worth worrying about, let alone even measuring.

On a single cam bow you can still get timing wrong. This is the rotation start position. Timing is always there but synchronisation only applies to twins where they need to arrive at the same time.
If you had a broken string or cable and fitted a wrong replacement to a one cam you could find you have lost draw length or the modules didn't give the lengths they were supposed to.

Yeah that's pretty obvious, but there is no "timing" of a single cam (despite what ArcheryTalk "experts" claim). You can change the rotation, but there is nothing to time it too.
Adjusting the cam rotation of single cams is essential to fine tuning the draw length, but won't have an adverse effect on the consistency of the bow. In other words, it will still stack, even with a cam adjusted 1/2" out.

Timing, or sync, is required on twin cams, hybrid cams and binary cams.

We are talking about the same thing, but in your original post you talked about adjusting both cables, there is only 1 cable on a Triumph, along with one string.
