[Austin W Hogan]

A 24 x 24 square has 81% of the area of a 30 inch circle; the corners extend outside of the circle, and there are four little crescents of the circle that are outside the rectangle.

Dividing the 24 x 24 square into 16 6 x 6 squares would allow 1 square to be counted and multiplied by 19.6 to get the number of shot in a 30 inch circle.

Dividing the 24 x24 square into 6 8x8 squares would allow 1 square to be counted and multiplied by 11 to get the number in a 30 inch circle.

Applying random error statistics shows that a number of targets equal to the multiplier would need to be counted to differentiate the difference between the sample and the full 30 inch circle.

I am sure King figured this out quite quickly.
