He really should have a go at getting himself on the leaderboards, especially since he's trying to perfect his times and has a total under 9 minutes. Even if he could be cheating, it's likely he could get himself somewhere at the top, if not the top of the leaderboards, if he did it properly.
Though if he's content with doing so to make video guides, that's fine too, I guess.
Anyway, congrats to Jacky Durand on claiming top!
