I understand that 1/10 is a lot more than 1/1000, so obviously some of the highest percentages will be attributed to the smaller apps. However, when it comes to ranking these apps, do I go by 5-star reviews? 1-star reviews? The ratio of reviewers to downloaders? How would you go about this?
I thought about the equation of (r/d) * p = x, r = total reviews, d = total downloads, p = percentage of 1-star reviews, and x = rank value, but the download amount is approximate.
