Calculators forgot perspective (angular size)

Flat earthers may have made a BIG mistake by never seriously questioning the curvature calculators. I could be wrong but I did try to ask some serious globe believers who refused to respond to my request (by itself, I find that interesting). Simply, the calculators forgot perspective (angular size) and the change is potentially HUGE and may forever destroy the globe (at least for the objective truth seeker). Seriously, it seems as though entire large mountains like Denali shouldn’t be visible within a short 50 miles of the observer in accordance with the official ball model; large 20-foot boats shouldn’t be visible within 6 miles from the shore; the Statue of Liberty shouldn’t be visible within 13 miles.
