How your three scores become one number

The overall score is the weighted mean of your three scores (Performance / Utility / Reliability), shrunk towards the site-wide average using a Bayesian prior of 5 votes. That is why a car with two votes never outranks a car with two hundred, and why a single angry score cannot sink a popular model.

Current site-wide mean: 3.5/5 (7/10). Your rating is stored with the three integers you pick, an optional note, and a timestamp.
