What it cannot know

Grading outcomes are decided solely by the company you send to, not by this model. We cannot guarantee a result: condition is specific to your copy, and we have never seen it. Scores are projected from publicly available population and sales data, and the thresholds between the bands are our own judgement rather than an industry standard.
