Using Matt/PA's example......of the arrow line and the sight line meeting at 8yds (+/-....it really makes no difference where these lines meet....as long as we agree they DO "meet" at a relatively short distance.....prior to 20yds)........It would seem, to me, that the lines intersect at 8yds (naturally).

My question, again.....is...is the line thorugh the nocking point....the arrow tip....and the target at 20yds a straight, levelline.....and "compensation" made by the arrow drop beyond the 8yd intersection point?

Again....it would seem, to me, that the line from the eye.....through the peep.......through the 20 yd pin.....to the spot at 20yds.....HAS to be "straight".
