I tested for curvature mathematically
what math. I don't care about your data yet, just the mathematics you used.
a = √[(r + h)² - r²]
where:
a stands for the distance to the horizon, h is your eyesight level, and r is the Earth's radius, equal to 3959 miles or 6371 km.
you calculated the distance to the horizon and then measured it?
www.distance.to gives ‘as the crow flies’ aka direct distances.
