What these numbers mean
The counted sample is the sum of Just Eat’s five rating buckets. Its published explanation describes a median score from the previous 12 months. The broader total includes ratings outside this sample; these aggregates do not tell us why each rating was excluded. Buckets group half-star ratings, so the 4–5 bucket percentage is not an exact count of individual four- and five-star reviews.
11% fall in the 1–2 star buckets. Our “Often terrible” label means more than 15% fall in those buckets, with at least 20 counted ratings.
Its Eat Score is 56.5 out of 100. The Eat Score is our own measure, and higher is better: it is the Bayesian-adjusted share of counted ratings in the 4–5 star buckets, minus the full adjusted share in the 1–2 star buckets. It is not Just Eat’s rating.
