Welcome to this disgraceful representation of a "speedrun" in which we completely take out a valuable element of time management, and replace it with a roll hover / superjump chain that takes several minutes in real-time to set up just to deload the hourglass and effectively max-out in-game time. In fact the only element of speed represented in this "speedrun" is holding the Triangle button for about 3 seconds.
And in the worst timeline, if you are seeing this now, it's allowed for a Speedrun leaderboard submission. Probably as a permanent WR for this IL, even though there are many other runs out there that are actively faster than whatever horrible stuff is portrayed here.
Look away if you must, you're about to witness the dark side of Sly 1 Master Thief Sprints
