Thanks guys. I did paper tune last night and found I am pretty much shooting straight through. When I did get a hold of the archery manager on the phone from the shop where I bought it, he said its common for it to have a slight angling downward while sitting on the rest. And several set-ups from others that I have looked at since then have the knock loop ever so slightly higher so that the arrow is at a slight decline on their rests too. Just overthinking it I guess. But better to overthink than miss opening morning.
