once your form is good, start picking spots. Then go back and fix your form, then shoot some targets(of some sort), then do it all again. You will find that you think you have the proper form until you read again what you are supposed to be feeling or doing, then you will figure it out even more...and so on, forever. So basically it is likely that you will get more and then less accurate and then more again in some sort of cycle until you quit shooting. Usually over-thinking it and shooting when you are tired are bad things. Over time your consistency should be good and maintain if you keep shooting.
