John would have beaten both Willie Mosconi and Mike Eufemia's record as well.
I read elsewhere here on AZ, that Mike Eufemia run of 625, and cited in Guinness Book of World Records for highest run, but not an official record.
February 2, 1960 (Tuesday)
At an exhibition at the Logan Billiard Academy in Brooklyn, Mike Eufemia set a record that has remained for half a century, for the longest "run", sinking 625 consecutive billiard balls without a miss.[2]
seems just a tad odd 626, exactly 100 more,
would be awesome if true, but so far no confirmation
