Agree completely. In order to just fire away without sufficient control of what you are doing, it would take some luck almost beyond possibility to run 500/600. On page 2 here I said probably 250 to 350 in his higher runs, just for this reason. These runs themselves are way beyond most who ever picked up a cue in history, a testament to the great ball pocketing ability, and maybe the table set up to a degree; I would be surprised to see even a 400 if Sunday is his final day at this.He has a chance, perhaps the best chance of all the top 9 ballers, however it's a long shot. A week isn't all that long. I think, whomever really wants to beat the record needs to set aside some serious time to practise to get into the groove, before showing up.
I remember an earlier thread were people claimed that any top 9 baller could shatter the record at will. At least this will show them it's not quite so easy...
I think some of the 9 ballers would need to spend several months concentrating on 14.1 to really get into the right mindset of how to control the cue ball and stay out of trouble so that this 14.1 aspect balances out their great shot making ability. Absent great awareness of that cue ball on EVERY shot, they are not going to just show up and run 600 balls unless Lady Luck is very generous one day- table set up aside. IMO
