Yes and we keep asking how do you know it is level, you say hold a level over it like a spirit level, we ask what the amount of curve would be and then you waffle.Argue as much as you feel but no matter what distance is chosen it's always going to be level.
Meanwhile you talk about your approximation of a curve of 8 inches per mile squared but refuse to apply this to your water level 'proof' because even your own rule shows the difference over the length of a bath or spirit level is in the microns which can't be measured with a spirit level and the naked eye. At that scale a spirit level is not even accurate enough.
Basically if this is your main proof, it is no a proof at all because your own argument negates it, which is why I say you have a tangled mess of contradictions.
While it is true that the rule is wrong, it is pretty close under 4000 km that as a rough guide it is fine to use.By saying "Fall per mile squared" you're still showing that you don't even understand the maths of curves.
"Something per SomethingElse squared" is the formula for a parabola, not a spheroid.
You're still just closedmindedly clinging to the acquired knowledge you've been brainwashed with. These are nothing more than stories that were written by The Man that wrote the Flat Earth guidebook 200 years ago, and you're just repeating them back to us like a happy parrot
It clearly falls down if you are trying to measure a curve in microns over a very small scale, very very accurately. But even over 200 miles the difference between the rules is only 78cm so if you are talking about the drop to a building that far away (and it would have to be a huge building) does the square rule predicting you should be able to see 78cm less, really matter?
If it works for him over the scales we are talking, I'd say go with it. Lets see if he can use it to calculate the drop of a spirit level over the length of a bath.
