Here's my most recent PB for the Math% category. Absolutely fantastic chapter 1 up until the calculator grind, which went horribly. There is about a 7 minute section in chapter 1 where I had to leave suddenly to take care of my kids, but I paused during a cutscene, so I doubt that matters much. Overall, 7 randoms and 13 extra math turns, but only a few spots where luck just wasn't on my side, plus no scrollable Orlandu. Even so, sub 4 definitely seems possible now!
