This is similar to my other thread on introducing an expiration date on data. In the section where it says, "Top 10 languages spoken by your channel's audience", I had a MASSIVE amount of traffic from India over a year ago. Hindi is THE #1 language for my channel IF you count "all-time views." This is fine and dandy but this is not the case at all anymore since my traffic is now primarily older, English-speaking Americans. So while this is still the case overall, it doesn't at all give a picture of my channel's running average.
