In this note, my objectives are to clarify the ideas in a previously published quantitative verification and validation (V&V) approach that is based on experimental uncertainty analysis concepts; to suggest a new viewpoint (and nomenclature) for assessment of the results of V&V efforts; and to discuss an inherent ambiguity in the interpretation of results of grid refinement studies that are used in verification approaches.
