I don't really know what the answer is because it would depend on the market.
If I am in a highly conforming PUD project and the appraiser is off by 3% using the best comps available because he never called the agents involved to find out every sale used was part of the Nehimiah or AmeriDream program, I'd disagree with the value, regrid them, and come in 3% lower.
But if I am reviewing an appraisal like the one you have that is for $1,450,000 and my numbers are coming up with $1,392,000 or maybe even $1,421,000 with comps range from 1.1 to 1.6 (or are inclusive of the $1,450,000), I think I am just going to be commenting on the adjustments made, that they are unique and inconsistent, but then agreeing with the value. If it is an obvious push I would likely comment that the adjustments appear to made in a way to appraise the house at the upper level of the value range, but the appraised value still appears reasonable.
I am not big on reviews. Some lenders are very good about wanting quality reports and look for quality reviews, especially the lenders I work with; however, the report seems to be written in a way to simply acheive the end of having two appraisers on the hook for the opinion of value. Maybe I am just paranoid.
