It is hard to describe. When you throw, you don't line everything up. When you shoot a handgun real close, you point it, not aim it. When you use a pea shooter you just blow it out.
As above. you have to look at what you want to hit, a small piece of it, and your mind takes over.
Try making a smaller mark on your target to aim at. The term aim small / miss small comes from that and is very real. Stay very close until you master that range, then extend by playing.
and. . there is nothing wrong with aiming techniques
