This ended up being the most nightmarish track in the game to save time on. About 20 hours of attempts and I couldn't get anything lower than a 55.65. I then went and programmed a TAS and realized there was more time to save. Did more testing, pulled out some tricks, RNG played nice, execution was on point, and we got a good time. Enjoy my freak-out at the end for getting all 21 records ;)
