Hi Danny. Would like to start out by saying that I love your game. You are a great player.
About your question. What reason would the people who seen, and verified the video to be authentic / legit have a reason to lie about the authenticity of the video / the 626 run? As others have probably mentioned, I do not believe that the 626 Run is going to do anything for the popularity of pool or the game of 14.1, so that is why I do not see any reason for anyone to lie about the authenticity of the run. It is an amazing feat that John Schmidt accomplished, but I do not see it helping him much financially, or helping the popularity of the sport, or 14.1 much, if at all.
I do wonder though, what is your high run in 14.1?
I do have a lot of respect for the game of 14.1.
