You sould be able to see the spot verticle or canted. You may need to check whether your right eye is the dominant eye. if it is, you should check your "line". is the arrow alligned with your spot as you draw? it's not if you can't see the spot or the arrow. OK, we don't focus on the arrow, but it should be in the peripheral vison of your domopnant eye, as the spot shout be in total focus. If you are blocking the spot with the bow, you must be angling the bow out of line. The "line" is everything - from your eye to the spot, from your elbow through the arrow to the spot (adjusted for elevation.
I bet a $ you are left-eye dominant, as the test is to close the left eye, and if you are right-eye dominant, the spot is in your vision, as you are looking at it with your right (dominant) eye. If you close your left eye and the spot is blocked, you =were using your left (dominant) eye to see the spot. Close your right eye, and you see the spot - left-eye domimanat.
Anyway, if you really are right-eye dominant, and are blocking the spot in the verticle, bend your bow arm more, so it moves a little right, and you have a good "line" to the spot.
