I realize this, what I'm saying is that if the first person above the group of 0-0's with the same score has a rank that isn't 1 rank higher then them, that could mean that the bottom rank that everyone is tied for is the total number of users.
i.e. If 5 people are tied for second the next place would be 7th. But if there were only 6 people competing there would only be a 1st and 2nd place...sooo, it's probably like that here and you can't tell how many people total there are.
