So I improved my segmented 1%. Now I'm having more troubles with room strats than with Yakuza and Nightmare. Didn't die to them, but died to the same pirate twice on the way to Nightmare. Then to a bunch of random things in sector 4 after nightmare. Haven't decided if I'm going to try to do single segment attempts, or try to do optimized segments. Probably single segment attempts with safety saves still.
