If you add up all the world records on the IL leaderboard, you get 12 minutes, 42 seconds, and 12 milliseconds as the best time on single segment. Though, getting all the luck and execution makes it probably near impossible

NOTE: It's actually 120 milleseconds, sorry.

It may be one of those "One in million" chances but never say never. You could find out that in ten years someone might even surpass this theoretical best
