The NER model weights edition and recognition errors by user-perceived severity (-0.25/-0.5/-1), treats 98.0% as the minimum acceptable live-subtitle accuracy with bands up to >99.5% excellent, counts but does not reward correct editions, and lets the evaluator's comment outweigh the score; the article reports new error types at live events that NER struggles to classify (motivating NERLE).
