I object to their methodology. They are including the sides of the pancake to model the pancake as having a plateau-like topology to conclude that it's "not flat". Clearly the pancake being referred to in the adage "Kansas is as flat as a pancake" is referring to the interior region of a pancake that excludes the edges. A more appropriate methodology would model only a Kansas sized interior of a larger North America sized pancake, without the cliff-like edges.
