How the points work
- Rating100
Public ratings, pulled toward the average when there are few. Shown only as “Highly rated”, and only where the rating matches the company by its phone or its own city.
- Points100
Numbers are compared with the other companies on this list, so the biggest firm can't run away with a signal. A company the data doesn't cover gets the list's middle score for that signal, not zero.
