Get one yourself and do it. It's the only way. I'm telling you. I'm not trying to be rude. Find someone that has one. P900 is fine. Find something 20+ miles away. Do the calculation. It doesn't work.

The calculation is easy 8" per mile squared.

Find a lake. Get a buddy and have him stand across it. Or in my first case. I found an exact same altitude spot and zoomed in on a tower building I couldn't see over 20 miles away. Guess what, I could zoom in and see it.

Repeat as necessary. Don't believe anything you see or hear. Do it yourself.

This was my first step. It blew my mind. I then went on for a year learning about the lie. Like I said, I don't know what it is, but it's not a ball.
