either i'm confused or you guys are.
For me, personally, the question is who is the greatest 14.1 player of all time. Correct?
To me, a high run has very little to do with who the greatest 14.1 player is whatsoever.
To make my case, I'd like to cite a similar type of achievement in the game of golf. I use golf because it is an individual sport in very much the same vein as pool. 3 or 4 players have recorded 59s as the lowest round ever recorded in a PGA event, David Duvall being the last one to do it. 
Tiger Woods and Jack Nicklaus NEVER recorded 59s in a tournament. Would anyone argue that Tiger Woods or Jack Nicklaus are not the two greatest golf players of all time? You'd be hard pressed to find a good argument against it. 
14.1 is supposed to be a competitive game between 2 individuals, its not about one person at a table alone. The greatest 14.1 player of all time would be the guy who has won the most 14.1 titles and defeated the greatest players. To me, that's Willie Mosconi. 
The high runs achieved by Ralph, Willie, John or Thorsten are all incredible feats that should be commended, but if they were recorded outside of competition it tells me absolutely nothing about their will to win, their competitive edge, etc. 
Willie's achievements in terms of titles won, etc. is unmatched in history and it's pretty tough to me to start talking about John Schmidt even in the same breath as Willie as a champion.
