Miller excellent work so far!!! As for being accurate, it will come. Thats why I stress to keep your eyes closed while doing this, results will come but not instantaneously. What you are doing is actual practice! I would suggest doing this 25-30 times a day with your EYES CLOSED for a couple weeks at the least, the biggest part of being moreproficient is the COMMITTMENT to learning it, ifpeople really want to get betterthey'll put in the time PRACTICING not shooting, if they are not, they will be shooting groups in as little as a few hours looking for the instant result. The others are correct, even just a pic from front, back and even above, usually a mirror on the ceiling when avail will help see your form better.
If you are not shooting in a league right now and stick to eyes closed there are some aiming practices you can do after some time.
