I think the only ranking that is important is comparing yourself to yourself. Are your scores rising or falling?
Even then, the numbers , themselves, are not so important. They don't have an effect on what you are earning. They don't have much of an effect on how much people like your writing.
You can see that a lot of writers who are active and consistently produce good content, usually have high scores-- but they also often go up and down.
Concentrate on doing good work, along with some participation and interaction. Let the variable numbers fall where they may.
