They do some strange form of averaging, not all of which is obvious to the shopper. 5 is the top of their scale, so unlike with the SASSIE system, you will never see a 10 or anywhere close to it. A 4.7 with CoRI is perfectly respectable so don't waste a lot of time worrying about it
In the long run any rating system is more an indicator of your reliability and ability to properly perform a job. And while we all were accutely aware of our classroom grade and GPA in school, the rating systems tend to be more arbitrary. But obviously if you are doing good work for a company they will try to keep using you when possible.
