99.9% of calculations based on the assumption that the Earth is flat
work out just fine.
When I first noticed jogs in Indiana back roads, I assumed that they represented the wrinkles that appear when flat graph paper is smoothed
over a sphere. It turned out that the jogs were seams where different
surveys met and all the tiny little errors added up.
A planet is a big place.
