Cargo,
Was the bow initially in synch at rest and also at full draw right out of the box? I' m assuming that you are following the timing marks on the cams.........you are assuming that they we' re drawn correctly at the factory?
For right now forget the drawn on marks, and use the cams themselves for at rest measurements. Find a land mark that you can relate to on each cam and measure that landmark in relation to another static object on the bow (limb fork edge etc.)

Try that and see what you find.
