Those round earthers - have formulas after formulas to claim the earth is round, so they have every basis to claim the earth is round because they found formulas to every flaw, such as:the earth is tilted, the moon orbit is tilted - you can do it for every kind of module, you can provide formulas for every kind of module and for centuries based all the world according to the module.
So measurements are based according to the modules therefore don't try to prove flat earth through measurements, they are already corrupted.
I have my measurements - I looked into one of the satellites famous maps and calculate within my head and emotion if the measurements are valid. and they are not - try it yourself, walk for 200 meters according to satellite map and tell yourself if you walked 200 meter.
Look before you walk this distance and see if it really look like 200 meters - I am telling you, I looked a 200 meters distance according to satellites and it looked like 1km at least.
My theory: the vastness of space, earthly space is stretching while you walk and proceed in space, this means that a building you look at is not exactly how it looks and how much space it take.
when you walk your vision and your timing is in slow-motion but if you look behind you, you may see you have walked much more than if you look forward.
