even shooting arrows not matched to the bow, they should all hit in roughly the same place if form is consistant. you won't know if your arrows are match or not, or if it's your form unless you can keep them in a group. pick a spot and shoot three to five arrows. if they are grouping, your form is ok. if they hit right, your arrows are under spined. if they hit left, your arrows are over spined. missing up or down is probably your nocking point in need of adjusting.
