"Accuracy" should be associated with a standard or benchmark (no pun intended). Otherwise, "accuracy" will have different meanings to different people.
(There is a standard for color accuracy of still picture cameras called Imatest. People use this to determine the color accuracy of a camera under review. The deviations from accuracy are ultimately displayed on a chart.)
I no longer use the term "accurate" in an audio assessment..... I might *think* it's accurate, but that does not mean it would perform well referenced to an established standard, if it were to exist.
