Hi,

We're looking at the reviews endpoint and trying to make sense of the average ratings received over all the reviews and the average rating we're seeing on the Google search UI.

In the case above, one would expect the UI to show a rating of 5.0 (since all reviews posted have a rating of 5) and not 4.8. What is going on there?

The core of the matter is this: They use "Bayesian statistics"
