What does the signal score of 54 mean?
It's how well reviewed Plank Firm is, out of 100, next to the other mattresses here. Two things go in: how its reviews compare with the best-reviewed product (positive reviews, mixed counting half, and how many reviews there are), and its own negative and mixed reviews, which take points off, so only a product few people are unhappy with scores in the high 90s. It's worked out from reviews only, needs at least 5 of them, and updates as new ones come in.
