Is total points really due to player activity alone?

[wonderpug]

Exactly. There are many things that contribute to how many points you gain or lose. When you look at a point total, though, you have no way of knowing which of those many things contributed. Did they win those points in Fluffy league? In Super Titan? By winning a smaller number of high point games, or by winning a large number of low point games?

The only thing you can be sure of is that someone with a high point total has played a lot, which is why people say that's all that points say.
