Guild Wars 2

Can someone please at least answer these two questions?

Am I playing the right kind of games? In the pvp lobby I press the crossed swords icon and select Ranked Arena

Have I played too few games?

It should not be too hard to answer..?

How does the pvp leader-board work? From what I have read you should be able to see yourself on it if you have played 10+ ranked games? I played at least 70 but still can not see my of standing (neither place or percent) I created a new account for HoT and tried there too played 20+ games but I do not show up at all, I can only see myself on the achievements leader-board not the pvp one.

Am I playing the wrong type of games? In heart of the mists I press the crossed swords icon at the top middle and select the ranked button.

Have I played to few games?

Is it just bugged?
