Gametracker is not as accurate as it may look to you. I've been playing on the server with different names every now and then, whenever you use another name than the name you originally use you will start all the way from the bottom again in the ranking list. For a fact, if you fill in my name 'Paralyzed' in the search field there's 5 names that I used, counting those up all together gives me the following results (this is still not as accurate as I also used other names than just Paralyzed, but we take this one for example now):
- Time played: 522,08
- Score: 42900
