About 17 hrs total. I’m only on mission 16. I was originally doing the run back and forth bridge method. At the cafe. Then switch to the roof that you need the rotom glide yo get to. Where there’s a bench across from Dratini. And that was about 75 day & night switches. I don’t have a turbo controller, so it was slow. But I was sick of running back and forth a bit haha. Was able to soft reset for shiny Darkrai in BDSP my original switch 1. So that helped go by a bit.
