So did you arrive at the perfect tear as a result of moving your nocking point and/or arrow rest? If you did, and you wound up with the nocking point a little low of perpendicular, does the bow pass the other tuning tests? Like walk back and BH vs field points. If it does, don't worry about it. Most of the time, though, the perfect tune spot winds up with the arrow rest about 13/16" of an inch out from the riser (+-1/16") - arrow right down the middle of the Berger hole - and the nocking point about 3/16" above perpendicular. But it is what it is . . . unless there is some other issue going on - like incorrect arrow spine, fletching clearance, cam timing, etc.
