> Most projects are average by definition. Otherwise that wouldn’t be the average. You're assuming outliers in both directions don't dominate the process. As an example, let's say we have 10 projects, that have some property that can be rated on a scale from 1-10. Difficulty to accomplish is the first thing coming to mind. If we have 5 projects that are a 1 on this scale, and 5 projects that are a 10, the average is going to be 5.5 despite none of the projects being anywhere close to that.
