RE: String/arrow/sight lining up?
This is very common on bows with cable guards, especially shorter axle-axle and high let-off bows. As the bow is drawn, the cables take most of the tension as the string lets-off. This creates a moment applied to the cable guard which torques/twists the riser clockwise when looking from above. This brings the pins around a bit and most likely everything lines up at full draw.
