Setup / nock height
 

I had my bow set up at the shop when I bought it a couple years ago. I have started to get into the do-it-yourself stuff recently, and I have a question about how mine was originally set up. For starters, the bow is a Reflex Highlander (cam 1/2) with a Octane Hostage Pro rest. I recently read Greg's sticky about installing nocksets and loops, and noticed that he sets is nock height so the arrow is perpendicular to the string when nocked. This makes sense to me. However, when I nock an arrow on my bow, the arrow is not perpendicular and is pointing downward. Is this a reflection of the bow being a cam 1/2, or was it not set up properly? It shoots just fine, but I am a perfectionist and want to have peace of mind. Should I lower my nock or raise my sight so the arrow is perpendicular and lined up with the berger holes?
