Sub 15 will never happen. It's literally impossible. A lie, a myth, a farce propogated by the government to mislead the ignorant. Anyone who thinks it's possible is stupid and should feel ashamed, and can wallow in their own lack of intelligence. This is an irreversible fact of speedrunning and simply cannot be challenged. Go cry about it, nerds.
