The best way is what works good enough for your objective. Pie plate accuracy at 10 yards is good enough for some. Others might want to extend that to 15 or 20. Still others want to shoot groups that put fletching together at distances they considerable reasonable in the field or on the course.
Of course there are some who poo-poo the group altogether.
For me, I want to stack arrows at 25 yards. I'm not there yet.
I have ZERO doubt that I could put a sight on my curve and reduce my group size by a very significant amount. In fact, I've done it for a few minutes. Then I quickly put that bow up so I won't give up shooting barebow.
I thought I shot instinctive when I was a teenager and before 1975. I believe I was really a gap shooter. Now I'm a string-wallking point-of-aim shooter.
One thing that is pretty true for a lot of folks, if you are using an aiming point (sight pin or point of the arrow) and try to force that point to be still on the spot you want to hit while aiming, you are in a counter productive battle. Movement is a good thing.
Also, if you insist on practicing one of archery's myths that the bow arm should stay up an still until the arrow hits the target, you are failing to allow natural follow-through of the bow arm.
I also realize some believe I've written at least 12 too many lines about aiming and have over-complicated the process.
