Its not valid because it adds things like cracks, dead plants, patchwork repairs, rust, random utility boxes, loose cables, etc. Its won't tell whether a place will be maintained well. It gives you more of a worst case.

I figure that’s an architectural in-joke. The engineers will add ugly stuff because you didn’t consider stuff like HVAC or electricity.

Fortunately, you have one of the world's most powerful supercomputers sitting between your ears, so we don't need to compare this to nothing.
