    100km/h train = 4 hour journey 200km/h train = 2 hours 300km/h train = 1 hour 20 mins 400km/h train = 1 hour 500km/h train = 48 mins 600km/h train = 40 mins

    It feels like you’re scoring returns logarithmically as you move the scale additively here. The faster you go, the sooner you arrive, it’s simple and linear. I’m not actually sure if acceleration and deceleration has been a big issue at the scales involved.

    Edit: As is the author. Really, added cost per added speed is the important function, which isn’t gone into in any detail.

      Yeah, how is it so unbelievable that when you go twice the speed you are twice as fast but when you go a third faster in speed you only go a third fast in time. Diminishing returns is something else, like you would go a third faster in speed but arrive only a quarter faster.
