is there anybody who knows about 'field of view' for shots?

i I happened to learn about the presence of viewing angles while working on shooting with trainer settings on.

When the shooting trainer is turned on, the target is formed at the target point when shooting, and the size of the target varies depending on the angle at which the shooting is performed.

At first, I thought the size of the target varied depending on the angle formed by the difference between the player's direction of movement and the direction in which the ball shot moved, but that was not true.

The size of the target seems to depend on the angle formed by the difference between the line indicating the player's direction of movement and the center of the goalposts on both sides and the line connecting the player's position.

The angle minimizes the size of the target within about 60 degrees.

In fact, based on the fact that a valid viewing angle for humans is 60 degrees from side to side, I estimate this angle as a viewing angle.

So far, my findings have not been firmly verified.

I need your opinions.
