No one argues that ANSI is 'hard'. What we argue that it is pointless. It is also another "gotcha" where someone can (and almost certainly will) argue that you were "wrong" - perhaps by as little as a couple of tenths of a foot. And, again, the "precision" of your measurement is not a measure of its "accuracy". Any surveyor would laugh at the crudeness of our methodology. No level, no tension, no true "targets"- a clipboard maybe held up to a rugose edge of a rock or brick building.
I used to have a cat. That cat would stalk a mouse and then pounce upon the clump of grass the mouse supposedly was in. Sometimes he came up empty and then proceeded to swat the clump of grass around as if that were his primary goal and he never intended to catch a mouse. This is the same. You fix a real problem (inaccurate sketches and SF estimates) by clarifying that you need some more systematic method of measuring.
First off, the primary sketcher of record is the assessor. Realist does not sketch. It is a secondary source, only regurgitating the SF posted by the assessor. Secondly, a Realtor MIGHT measure but normally, unless the homeowner shows a previous appraisal to the agent (which might only be a copy of the assessor's sketch) agents are discouraged from measuring themselves because of potential liability. The attorney for the state RE Assoc. even sent letters to the various boards urging them to not measure. I do see houses "sold" as SF that differs from the sketch and I even have measured one and found the assessor was exactly right whereas the agent had overstated the SF. How and why, I have no idea.
Third there is a lot of issues with really old houses. Tons of 800 SF homes had an 8 x 16 entry porch, which was enclosed and finished out. Eventually the assessor called it SF and so it became. Same with rear porches (example below) In reality, they could be segregated but in doing so, only complicates the adjustments with other houses....and needlessly so. It is used as GLA...so segregating it is making the case more difficult. And again you have that "out" about what do my peers do - well, they include it all.
The problem is not the precision of measurements. The problem is what is and is not being measured.

This house was remodeled by the preacher Osteen's half-brother who did things 'right' and sold well, then later resold and sold twice last year. I don't know who appraised it but it sold for $250,000 last time and as far as I can tell nothing was done to it since the investment company flipped it. It is absurdly over priced 100 plus year old house. And it is less than 1500 SF of "GLA" in reality.
