However, the microscopic properties of a crystal are periodic, so without more information I will respectfully decline to place the point. Here are the same points, including the new one you declined to add, superimposed upon a plot of the experimental charge density. The rat is exposed. Curiously, the points look squiggly now. No, it's an optical illusion that we can explore another time.
People are eager to extrapolate.
I had that impulse just a moment ago, but I exercised restraint. We love to look at small regions in space or time and extrapolate our observations beyond their range of validity. Knowing the local structure about a point in a crystal, we can predict the structure many atoms or molecules away. The crystal's periodicity guides us. Without that model, extrapolation would be a dangerous enterprise.
