I lost 3 seconds on Trial 18 with a dropped link, but that was the only big mistake. I made up for that with the perfect spacing on Trial 8 to skip the U2 cinematic, which requires near perfect spacing (Dash + Ultra can whiff or get full animation depending on exactly how you input the dash). Any other method of skipping the animation would take too long.

I was hoping I could hit 4:20 but I don't think that's reasonably possible for a human with current strats.
