The ROAR statistics aren't about you, and they don't say anything about you. They don't say anything about anyone. They are just numbers, and they are only useful when there are a lot of them.
Every game you choose not to record is a spit in the face of ROAR's potential. Suppose everyone did what you do? No games at all would be logged, and ROAR would have no function at all.
As I said above: if you think the ROAR statistics have value, then you should log all of your games. If you don't think the ROAR statistics have value, then why are even bother to talk about it like they do?
ROAR doesn't care if you're the best damned ASL player in the world, or the rawest newbie to ever climb out of the womb. ROAR doesn't care whether your dice were smoking hot, or you were playing with a splitting headache and can't speak your opponent's language. ROAR doesn't care whether both you and your opponent were cheating at every single possible opportunity. The only thing ROAR cares about is: what scenario were you playing, which side won, and (optionally) did you have a good time. END OF STORY.
