This seems to have a fundamental misunderstanding of Hacker News's front page. The goal is to have posts only show up for at most a day or two. I would expect 100% to be gone in a week.
The "outliers" are posts that were deleted and re-submitted, or possibly boosted by the moderators. The "visible for 44 days" post was only submitted 14 days ago; either it was deleted or it is a glitch in this guy's script.
