It seems to me that in the end, they claim to have better data than the
other sources. I would be curious what makes their data more reliable than
the "value guides" they mention. I did like the example they give for an
appraisal document, but it seemed to me they did a lot of the same things
that thier "methods" page pours doubt upon.

Where do they get this pristine data?

Best part to me was that if you go by published prices - you will be high.
So true.

OTOH, it doesn't matter what "average" is. That argument is fallacious.
