It's is your post rank. It isn't determined by any set number, but is relative to the posts of the other users. When it is full, you are ranked #1, and it's like the top 5 post count. If the top counts were 123, 154, 198, 278, 96, and 146, then you would need something over 96 to have the bar filled. Get what I'm saying?
Also, if you click on your username, and select "recent posts" then it will show you your rank, right under the title. You are currently ranked 8.
