We just launched our new Rating System. It’s important to note right off the bat the reviews still use the same five point scale and rate the same six categories. The changes are in the way we determined the overall company ratings. We average all of the user ratings in each category to determine overall ratings and we used to display these numbers on a scale of 5 with 0.5 point intervals. The new system still averages all user ratings but will give ratings out of 100, which allows for better comparison between companies. The reason for changing is to make the site more useful and give you the best experience possible and we hope that’s what you find.
Here’s an example describing the benefit of the new system. Previously, Company A might have had an overall rating of 4.5 and Company B might have had an overall rating of 4.5. Because of our 0.5 interval scale, this means that each company’s exact rating could be between 4.26 and 4.75 but was rounded to 4.5. The new system will give more accurate ratings out of 100, so if Company A was really 4.26 and B was really 4.75, then the ratings will now appear as 85 and 95, a considerable difference!
