My only mistake was on 19, the jab links are all 1f so it's hard to get it first try. Luckily it only costs about 2.5 seconds if you don't cancel into headbutt. The rest of the trials aren't so bad once you learn the execution tricks to make Hundred Hands a lot easier. I could probably get a 4:16 with a perfect run, I don't think there's much room for more creative time saves with this character.
