I was looking at the reviews for an application which was rated as 3.5 stars in the summary.
From reading the reviews, there were few 5's a lot of 1's and very little in between. My "gorilla math" estimate is of the 50 or so reviews I read, it was probably averaged a 2.75 or lower.
How is this rating calculated? All reviews in history? Most recent? Some kind of bad review filter I cannot see?
