Example; do I take the 08:00 train or the 10:00 train to Berlin?
It's the ICE train with a punctuality grade of 62.5%, meaning over a third were late. Aka the 10:00 train is risky. But the 08:00 train is early and my hotel is in a completely uninteresting part of Berlin, aka there's a good chance I'll just be in my hotel room for a few hours until dinner, so I might as well sleep in.
