If you are talking about the fact that you spawn in the other room after being spotted, you can trigger that consistently. It's not only a switch thing, I tested it on both pc and Switch and it always puts you in that room. The spawns in the Express are kinda all over the place, same like the metro.

100% > 110% / The 10% that come after getting 56 time pieces, are the progression of the Death Wish map.

It's fun to learn the glitches, so I'd just recommend giving it a try. Otherwise just go with what the others said.

You lost interest quite fast.

You could try and learn the glitches. Speedrunning is about learning and it takes a lot of time.
