I think that what he may have been trying to say is that "the survey" does not qualify as "statistics".
Did I get that right, Kent?
Adding my own two cents: The information we've been able to glean from "the article" is anecdotal and subjective at best. What's more, by the time the survey responses were gathered, manipulated and turned into a report, synthesized by a reporter and now cited by you, the "statistics" you speak of have become third or fourth-hand.
C'mon..... we all know that surveys like the one you seem to like to characterize as "statistics" can not only be engineered to support a given position, but also have their answers manipulated for the same purpose.
Along different lines, there's a huge difference between asking an appraiser if he can validate a certain opinion ("the parties think the house is worth X, what do you think?" -- something Mr. Hummel characterizes as "dialing for value") on one hand, and a large lender (WAMU) telling its AMC (eAppraiseIT) to rewrite values on threat of losing hundreds of thousands of dollars worth of business (fraud).
