I'm still shaking as I type this. I was hoping for a 27:xx and knew a 26:xx was possible, but I didn't expect to hit it today.

Two new improvements: I found a more consistent setup for the skyrunner glitch at Pegasus Peak, which I happened to hit on the first try here. I also discovered that you can use the keyboard to exit your Inn room and skip the animation to open the door, saving 2.5 seconds per exit.
