Beware of not moving the aimer! At least look at it, preferably in reverse view because it isn't always where you think it is.
Here's a great "miss", one I've been using forever. On the flop shot, which normally goes right, as it should, try treating the first mark to the left of perfect as the ding mark. Now, don't move the aimer and use that as the ding and you'll be right on the hole. :-)
