I suppose you mean compared to the OA grid you posted - I believe my work would come off better than that though I do not claim to be perfect.
Idk what my comments about waivers has to do with the topic - indeed, every sale price becomes part of the future comps that might be used an AVM or CU- you concluded the OA value was "accurate" /agreed with it so that value , unless discredited later by another review stands - and the SC price is part of the sold property database whether for an appraisal, AVM, CU etc
