Because, as William explained, as did I in my "bracket" example, that the adjustment is explained in the text of the report.
"Barrister, Appraisal is an art, not a science." Become cocky and say "In an effort to not mislead the reader, as is required by USPAP, which incidently is FEDERAL LAW, I did not want to confuse the reader with the really difficult task of support individual adjsutments for many different site items, including width, depth, topography, view, frontage, etc., etc., etc.".
Pause, then state "the client ordered a summary report. As such, in depth discussions of such matters as derivation of individual adjustments for all of the site features was not within the scope of the appraisal."
Go on to say "the principal of substitution is what these adjustments are based on, and it is quite easy to see here that no 2 sites are completely similar in all aspects, yet similar overall appeal sites with differing attributes have been seen to sell for similar prices, and additionally have been seen to contribute similar value to the overall property value. "
Turn abrubtly to the jury, and say with a smirk "Therefore, Sherlock Holmes, the answer to your question is No, they are not equal, but they have equal contributory value."
