Just wondering why there's still over 1000 Gh/s @ Eligius (128 seconds 1,874.12 Gh/s)?

Probably to keep the queue to withdraw 41 btc..... If i haven't misunderstood the eligius payament system...
I believe if you stop mining altogether you will get a payout after 7 days no matter how small, so yes, it is likely to keep us in the queue so we get paid sooner than later.
