Haraguchi-san recited an amazing 83,431 digits of Pi during a 13-hour overnight stretch. This almost doubles the previous record of 42,195 digits by fellow Japanese Hiroyuki Goto. Though it is not yet updated to reflect the new record, the Pi-World-Ranking-List has the rules for participation and breaks down the ranking by world, continent, and country. Links to world rankings for memorized digits of E and Sqrt(2) are also given."
