A graph from 2010 and a stat tracking website that states "statistics are based off of 49,774 characters", yet when all the characters are added up there are only 15,813? What about the other 34,000? That is a lot of play, not sure if that could be counted as a reliable source. Guesstimation at best.

At best it could show a trend, but trends change from time to time. Especially when you take the beautiful unique snowflakes into consideration.
