Where it lines up will depend on where you anchor and how you hold your head. For instance, tilting your head to the side will change the pin position, or anchoring on your cheekbone vs. on the middle of your chin. In fact, if you want to see a really big move in the proper pin location, close your right eye and sight in with your left (for righthander). That will move your pin further left then many sights can even handle.
