Kinda funny how that comment is flag-killed, but an equally unverifiable anecdote is the top comment on the previous discussion, and it claims the same thing:
a lot of things are, I don't think it matters if it's verifiable true, it's a single n=1 anecdote anyway. The meaning comes from the reason it was mentioned, which I don't think is fluff.
That a difficult task might be possible using an unconventional method that the competition designers didn't anticipate. Again, I said believing it isn't necessary.
