This pattern for Pac-Man's strawberry board was the fastest that I knew of when I created it. It runs 66.8 seconds. It was used by David Race to set the world record for the fastest perfect pacman game in March 2010
David Race has since come up with a new ending to the pattern which shaves a few seconds off of the time.
