Their methodology would make anything look flatter if it was covered a bigger area. I wouldn't be surprised if mountainous states like Colorado would look flatter than a pancake with their method. The mountains there are less than two miles higher than the valleys they rise from, which is less than 0.5% of the width of Colorado.
