Being seen - do you like your name in the charts?

I'm thinking of a positioning chart (like a highscore chart) for my browser game - but here's the thing, it'd have four special highscore positions that can't be won by anyone else for say a day or two after they've been won. So there would be a top ten and you could work your way up - but so could someone else an hour after you. But get onto the four long term charts, the fourth position has to be free to get on it. Then the third has to be free for you to work up to it, etc. But the big bonus is you stay there for a much longer time.

But you have the top ten so you can get somewhere as well.

All this and your building up your fighting skill, which will be shown next to your name.
