It would be best to be directly under your eye, but you might find that it's hard to "see through" the string and actually use the arrow to aim if both were perfectly aligned. I align the string blur in a consistent place along the inside edge of the riser, where I can just see the shaft running out aligned with the string on the right edge of the shaft. That works for me, and I had to play with my anchor and string alignment quite a bit to find this position. Until I did, I would shoot left consistently.
