I made a montage video showing some 3 runs on various settings. This is to show tricks to improving times overall. But also the differences in NPC settings. Top: My quickest time on Hardest Time settings but Easy NPC. Bottom Left: My stock settings run Normal Time/NPC. Bottom Right: Kusanagi765 run with Easy Timer but Normal NPC settings.

You can see the volume of riders compared to bottom left. But if you look at tech you want to take bends has close in has possible since this seems to improve times. The sharp turns require you coming out of them speeding up to get maximum efficiency and taking them just right by staying in tight if a NPC isn't blocking you.

If you want me to do some more for the other courses or the home version I can do so using the videos from the leader boards.
