I saw that Sig was playing even though I was up kind of late already, but I just decided to stay up and watch for a bit anyway. Once he did DDD I knew that the run might be a keeper even though there was still a long way to go, so I stuck around. My faith was rewarded, because he beat the WR. Basically by the time he obliterated Nero's already amazing stair time, I knew I had to stay up for the rest. Totally worth it.
It's amazing too because there's still a lot of time that could make up. He didn't have good runs on WDW and SL, and RR was nearly a disaster (although not as bad as it was for Nero).
