Clutched the 5:02.6xx in classic Niftski fashion by having a bad first room fast accel and saving it with second room fast accel! I got this in only 7 attempts with the first run out of 4-2 getting it as well! Glitchless is now only 0.2 seconds / 12 frames away from the TAS, which is a 5:02.485. I do not plan on just stopping here, I would love to push this to a lower 5:02.6xx in the future since there are 3 easy frames to save in first room. A 5:02.5xx is possible with third room TAS accel + more accels, but if I were to ever achieve this, it would definitely be my stopping point.
Got my heart pumping just watching.
