I understand your point but sometimes it is useful for authors to take a little artistic license. They are clear on the ratings of the problems and the challenges of setting for the world cup. To an extent, these are the hardest problems of their type in the world...because they are for the hardest climbing competition in the world. Sure they aren't Silence, but most common folk would probably conflate 'problems for the world championship' with 'hardest' and to communicate to that audience the artistic license seems to me to have merit.
