Shooting is a mental and physical game - however if your head isn’t straight you can’t shoot well.
So 1) your accuracy at distance to be proficient must = or be smaller than your target size (target being what is your kill zone on your target).
Some people never get past that question which astounds me, on a deer one who shoots for vital zone “center of mass” has a big target so the pie plate thing works, being able to hit something smaller just makes you more confident.
Picking a smaller target say a squirrel - that is a heck of a small plate now isn’t it ?
