Made a mistake with the number of splits. For some reason I thought, that the epilogue is the fifth chapter (maybe because the number 5 was written in the titel of the epilogue), so I had a split for chapter 4, even though it doesn't exist. That confusion was also the reason, why I split late. But I timed the video again and 1:04:17 is the correct time. Run can still be improved. So, sub 1:04 should be no problem at all. But I am not sure, if sub 1 hour can be achieved with this route.
