Thus a 92%/4.6 rating means that 8% of the time, the drive doesn't show up, or fails to get to the right place, or assaults the passenger, or something like that. When you think of it that way, 4.6 doesn't seem as high.
Amazon gives a percentage rating, which is the percentage of 4 and 5 star ratings out of all ratings. I think twice before using a vendor with less than a 98% rating - too much of a chance that there will be a problem that I'll have to spend hours to straighten out.
If people actually gave a 3 star average rating instead of defaulting to 5 stars, things would be different, but that's not what people actually do.
I'm looking to see what drives the overall rating down a bit. 4 stars is pretty common there. If there are no 1 star ratings, it's probably a decent product. But if there are some one stars, it shows there might be serious problems.
Reviews don't commonly indicate how long the product of service performs before it breaks. Vendors often ask for reviews right away. Sometimes I ask this question, and get a few comments from people who have owned the product a few years.
