Wrong again.
Nope, you even say as much...

It just happens to be that 8" per mile squared is a good approximation using small distances.

It's a good approximation for ANY distance.

"It's a good approximation for ANY distance."

For NEARLY any distance, as long as it's smaller than the earth's radius itself. I'm nit picking, of course.
