The board might not have a great handle on certain elements of USPAP. First off, on the development side the SOW test has two parts: peers and expectations of other users of such assignments.
So if the board is concluding that most appraisers performing these assignments are not doing something in those assignments and never have then this conclusion will also strongly imply that most users using these assignments are not demanding that something. Otherwise the appraisers would have been doing it all along.
Secondly, on the reporting side the overarching goal is "meaningful to intended users and not misleading". I've been writing substantiative HBU analyses in my appraisal reports for many, many years and I'm virtually certain that most of those summaries don't actually get read. The exception being for land appraisal assignments and other situations where I end up valuing the property on other than it's existing use.
In lieu of explicit instructions in USPAP to the contrary, the ASB *illustrated* what - in their opinion - they meant in their use of the term "summarize" in an AO-38. The examples used to illustrate the difference in the level of detail between "state" and "summarize" have remained intact since they first appeared in AO-11 back in the 1990s, then were later rolled into AO38.
So while the way the URAR treats the HBU conclusion more closely resembles "stating" the conclusion than summarizing it, the equivalent level of detail for a summary of that analysis would not normally include a comprehensive and detailed regurgitation of the data such as the quants have been trying to sell to the appraisal profession as the one and only way to write an appraisal report.
So when a State Board buys into the hype and extends an expectation which is neither user driven nor peer driven (let alone driven by both) then I think they might be getting out over their skis a bit.
Now it goes without saying that AO38 is not USPAP and as such is not an enforceable standard, but by the same token it's unethical for a reviewer or a state board to attribute to USPAP an expectation for a level of detail which is not addressed in USPAP itself, and which does directly conflict with the ASB's stated opinion of what is/isn't a summary. These AOs are not necessarily the only way to handle a given situation, but in lieu of info to the contrary it would be hard to argue that the ASBs opinion as expressed in an AO will always be categorically incorrect.
IMO, it's extremely important for people to attribute to USPAP only what it actually requires, and to refrain from mischaracterizing our individual preferences as a uniform standard to which everyone else must comply. , The document only says what it says, and no more.
And however true that is for a reader or a reviewer, it's 10x more important for a state board to understand.
