@Kapy: Less because of free-time and more because I don't spend it wisely. :P But hey, at least I don't have time to troll the forums or write a screed about why the imperial Japanese flag is bad and clans using it should be opposed. Also coding during free time makes sense for me- since, y'know, ABC ("Always Be Coding").
Also, since the graph looked kinda quadratic-y, I tried a quadratic regression to see how well it would do. It's the thin blue line- and that line tells you a lot more than just "quadratic regressions don't work for this data":
