I'd like to see more info on the setup. Draw length of bow and draw weight. Arrow spine and length, tip weight and fletching type.
Most of my Martin bows have the rest set just about 15/16" from the sight window and my arrows are on the stiff side. I don't paper tune, but do bare shaft tune. What I'm hinting at is that your arrows might be stiff and need the rest set to the left to compensate.
One thing you might have happening is idler wheel lean. Have you addressed this yet? Usually with a RH hand bow the limbs are twisted with the top of the idler wheel tilted to the left. If yours is like this then you need to add some twists to the right hand side of the cables yoke where it attaches to the top limb. Holding an arrow along side of the idler and parralel with the string is a good way to check it. How many twists you might need is a matter of trial and error. I've had some bows that require 5 twists and some as many as 16 twists.
This is pretty common to single cam bows so don't think it's a Martin problem. Just one more reason I have gravitated away from single cam bow and back to dual cam systems.
This may not be a problem with your bow, but it is one thing that should be checked and corrected during any initial setup.
