Please provide any data that you have measured that says otherwise.
I've measure all the time, and I don't just use my own experiences to support my position here.
They are called atlases, nautical maps, gps, measuring my longitude and latitude by using the Sun to which is accurate and consistent with RE, the world school programs that measure shadow sticks across the globe, seismic activity dealing with S-waves and P-waves,(time, speed, and distance calculator), Earth's dynamo and magnetic field, and a shit ton of other sources
to which includes my own experience in sailing. I've also measured using my car and driving from Minnesota to Sun City Arizona to which was also accurate according to both GPS and Satellite Maps. You can even Use Google maps now to virtually drive around your own towns and cities. This is also accurate to GPS, satellites imagery, and the real world. This again is all accurate to time, speed, and distance calculations.
When you can provide me an accurate map of the FE world, you let me know. And I don't care if you measure it, or if someone else does. You want to make an argument, I suggest you provide me the data to support it, or at least provide 3rd party data that can equally be reviewed.
If you can't provide, then I understand that you have nothing to offer in this discussion.
