I didnt read all but from the little I did, I think its a common sense thing. The earth is too large in expanse to show any visible sign of sphere-ness.

the maths don´t lie, with a Pitagoras theorem you can calculate the drop for each mile with a radio of almost 4000 miles of the earth. so, you get 8in drop in 1 mile.
Well as long as you assume the Earth a perfect sphere.
