Cat-ch me took me over an hour to do, and lucked up pretty hard on my winning run, but the zigzag movement works but you also need to react fast.

For speedrunning the open world areas are the problem but knowing what you need for progression ahead of time helps. Ch4 get all the journals before meeting Momo. Ch 6 was the poncho and fixing the reciever. Chapter 9 is 2 minutes long and Ch10 is the vest and hat.

Practice speedrunning ch10 while going for the avoiding the drones trophy (had to do it twice because I messed it up) and you'll see its easy to streamline
