The Zone leaderboards are borked. They're only updating new scores, and they're overwriting the previous ones by other players that were much better.

The Syncopia WR was 16,000 points according to the board. I had a go at it and was put in #1. I only reached Zone 87 with 250,000 points... yeh, nowhere near the WR. The previous WR's position is now determined by the number of people who have played the track post patch.
