Nice work list.
"Johnston won the 1986 World Series of Poker
main event, and placed 3rd and 5th in the 1982
(http://en.wikipedia.org/wiki/1982_World_Series_of_Poker) and 1990
(http://en.wikipedia.org/wiki/1990_World_Series_of_Poker) World Series
(http://en.wikipedia.org/wiki/World_Series_of_Poker), respectively. He has made at least 26 final tables at the in the money
(http://en.wikipedia.org/wiki/Poker_jargon) at least 48 times. He has also cashed in the main event more times than any other player.
I think Hellmuth has the record for the most cashes overall, not in any particular event.
