In reply to ablackett:
> One minor editorial point UKC, you describe John's run as a record, but that Damian held the Fastest Know Time, if someone records the times, it's a record, lets use nice straight forward English so everyone knows what we are talking about. John has broken the record, to suggest that it is a FKT is like describing Everest as the BKM.
Not the best analogy, seeing as Everest can be categorically and unarguably measured as the highest. A better analogy would be describing the 1953 ascent as the FKA, or Honnold's most famous solo as the First Known Solo of El Cap.
There comes a point at which the likelihood of a 'better' unknown achievement is so vanishingly small it may, and probably should, be assumed it's never happened. The difficulty, of course, is in deciding where that point should be.
