The "Any %" category means that the final score of the speedrun is judged entirely based on the finishing time regardless of what was done. This is in contrast to a "Low %" speed run, where a low % actually trumps a lower speed.
This is especially true in the speedrun records of Zelda: The Twilight Princess. You can see that the Any % record is a little less than 3 hours but the Low % record is a ridiculous 24+ hours.
This video explains why the low% is so long, and it involves doing something really bizarre for many hours to skip a significant part of the game.
