The gutter could have been a foul. Wes Malott did that to miss a 300 a few years ago, ending up with 290. I think it was the week that Liz Johnson made the show, as he fouled several times on the show as well. WRW slides pretty close to the foul line, he could have missed by just a pinch.
As for the 8-1, it might have been a split. They don't mark splits, so you never know what the story was.
