Hmm, thats interesting. I forgot your shooting a single cam. I wonder if nock travel is playing an effect.

Basically with single cams, when you release teh string, your arrow does not fly perfectly straight off the bow. but due to the single cam design, it usually moves up a tad, then back down. Hense the reason, you have to adjust nock point 1/4" or higher than say a binary cam system.

Now the only thing that could affect this, is proper tiller, and cam timing. I have never owned a marquis, or set one up. But there should be some timing marks on the cam you or a shop can measure. As far as tiller goes, all anyone can do with a parallel limb bow is to bottom the limbs out (max wieght) and back off evenly to desired poundage. One can tiller tune, each time you take 1/4turn out of a limb, you have to readjust your d-loop. Can be tricky
