Certainly not trying to pour cold water on John's outstanding abilities...but, concentrating on breaking a world record, or any record, on a single set-up table/track/field, with repeated and unlimited attempts over months or years, is just not quite the same as creating a new record in a normal and natural manner, during competition, a game, tournament, event, or exhibition. It simply isn't the same.
Most "official" records, not including Guinness world bubble gum chewing records, are only valid if accomplished under the same, usually sanctioned and/or official circumstances that the original record was created under.
If a professional basketball player held the record for consecutive free throws made during regular season play, the playoffs, or the championship series; would someone who sets up a basket in his backyard and exceeds that number by one basket after years and thousands of attempts be credited with breaking the original record? Of course not.
I also understand that pool, as a sport, is not organized well enough to have enough "sanctioned" and "official" events to have accurate statistical data for all the various competitive levels like most major sports, nor does it even have official rules that can be used to determine how various "official" records are set. Perhaps I'm being too hard on pool and maybe it's unfair to compare pool to the "major" sports, but if we don't try and raise the standards we're willing to accept, we'll never move forward. Breaking a record in this manner just doesn't seem legitimate, not at all.
