Well, there it is. Finally got the sub 4:10. I don't think I'll be running this chapter anymore. It's too much of a pain to get everything right. I lost about 0.9 seconds combined to Triple Divide and Thread the Needle, which is a little bit of a bummer, but at least I finished the run. There's nothing much else to add to this run besides the loop exit on TtN, but good luck to whoever wants to add it. If you add that alongside a super optimized run, sub 4 minutes could be possible, but I sure ain't going for it. I'm satisfied with this.
