You're right that we should probably ignore San Francisco and a few others to portray the typical American experience.
But it's still not obvious why for example Atlanta (22.6x) has almost double the price-to-rent ratio of Milwaukee (12.4x) if not due to speculation. Those both seem like fairly "typical America" cities to me. Would you expect Rent in Atlanta to spike heavily in the coming years? Or is the distinction you're making more about urban vs. suburban? (Since my link is just a mediocre blog, it's not clear if those numbers refer to city or metro area.)
