Is total points really due to player activity alone?

Well, the player matching system adjusts so that you are expected to have a 50% chance of winning your games. That's the whole point of a player matching system!

So if you were really bad, you would be paired up against worse and worse opponents, until you had a 50% chance of winning.

If you were really good, you would be paired up against better and better opponents, until you had a 50% chance of winning.

The only exceptions are if you are the most terrible worst players, or if you are the most amazing best players (like me).

If you have a 50% chance of winning, on average, every 2 games you will gain 6 points.

So I think ultimately it is true that points are mainly an indication of player activity, in the long run.
