Though there are some things that remain constant, like everything being in alignment, consistent anchor and aiming method, back tension and follow through, it is my opinion that most everything else "depends". An olympic gold medal winner's "perfect form" may not be so perfect for a hunting situation on their knees, bow canted completely sideways, while an animal is watching, before the shot opportunity disappears. There are just too many personal variables to say one way is "perfect".
I don't stop to aim because aiming occurs even before the shot for me. Aiming is happening throughout the entire draw/shot process, I just don't do it consciously. Some use this method with great results, others with disaster. Find what works for you and hone it...if you can't make it work, try until you find a method that does.
Sounds like you are well on your way to developing YOUR perfect form, and that's what you should be striving for, again, in my opinion.
