A score out of 100. Negative and mixed reviews take points off, and so does having only a few reviews, so a handful of glowing reviews can’t beat a product many people like.

What does the signal score of 95 mean?
It's how well reviewed Fastmail is, out of 100. Negative and mixed reviews take points off, and so does having only a few reviews: a service needs plenty of them, compared with the most-reviewed services here, to reach the high 80s and 90s. It's worked out from reviews only, needs at least 5 of them, and updates as new ones come in.
