oh well... let me explain
Iam the only one who played some games (3 of 5 to be exact). No one else played because it's a private installation on my private webserver. BUT: this installation has some guestpostings in it.
When i look at a posting i made, i can see that iam the champion in 3 games. But at any guestposting i see that this guest is the champion in the other games. This can't be true because no guest ever played a game (arcade.php shows, that nobody played this 2 games).
Have a look at the image:
the first part shows a part of the highscore. The next part is the guest's postbit and the last part is my postbit
