JD Power - Top Auto Insurance Companies- 2010

How much stock do you put in these kinds of 'top' lists? It seems like they all have different criteria, some are based on thousand or tens of thousands of responses and others are based on fifty (or all made up in one person's mind)?

There are seven companies on this listing that my agency works with- two above the median and five below the median....but three of the five are within 10 points of the median score of 777....I should stop looking at these things and trying to make senes of them....
