Those estimates always seem hilariously bad. It's 400 alone to dead center. Consider it's 60 feet from home to the mound, does anyone seriously believe from where that ball hit that it does not at least continue past the fence the distance from home to the mound if unimpeded, which would mean at least 460 feet? Those measurements are a joke. The 60' 6'' from the mound to home plate is only six inches longer than the distance of a bowling alley. Yes, these distances are laughably underestimated.
