Because so many people thought my 890 was fraudulent and claimed it wasn't "truly perfect" because of the bumper rail trick, I video'ed a "truly perfect" rendition. The camera battery died on the last frame before the final score came up, but you see all the pins fall down and it does show that "91 pins" fell down. And fantastically enough, youtube's transcoding unsync'ed the audio, and clipped off a second or so from the end, so the already-short run just got shorter.
