Error Review Improves Through Repeated Passes
Error review usually begins with a rough first pass. You inspect a small set of mistakes, notice patterns, create tentative categories, label more examples, and then revisit earlier errors using the updated categories. If a new pattern appears, the categories can be revised and the review repeated.
