More accurate average project stats

[WorldLanguages]

First of all, I absolutely love the new scratchstats! Good job! 👍 There could be a way to make the average project stats more accurate. Instead of calculating the average of all of the projects made since the first day on Scratch, I think it should only calculate the average stats of like, the 30% most recent projects for example. That would exclude old projects that might not have a lot of views and loves, which diminish the averages. For example, it would only calculate the average of one's 30 latest projects (if that person has shared 100 projects, for instance). However, I think this should only apply to people who have shared over a certain amount of projects (6? 8? 10?), because an average calculated from 3 or 4 projects is pretty accurate in my opinion. Thoughts?
