It doesn't make sense to take the highest and lowest points because that doesn't take into consideration the "lumpiness" of the terrain. What if a country has a lower spread between highest and lowest points but goes constantly up and down vs another that is constantly flat (let's say in 99% of the surface), but has a highest maximum elevation (in 1% of the surface)?
Surely the latter is more flat, if the average elevation is lower than the former.
Hence, the average is a more significant measure of flatness
Whopper-
I see what you mean, but I don't think the average elevation in itself is the correct parameter to use as it just tells us how high above sea level the average is.
You want something like the lowest deviation from the median. :)
We need more data, but I can't provide it.
Edit: am just looking forward to some real mountains and proper racing.

No.
Flatness is not about average elevation.
Flatness is about smallest distance between lowest and highest points.
