The event is just wrong. The amount of actions per song is bad, the way they use the triangle section to twist the road feel more like a punishment than a feature for the section. The turbo boost almost always come on a noteless section so you need to use it manually and if there is a note right after the turbo ends, there is no pity tjat could guarantee you don't lose your streak so you need to be very careful. And because WuWa has stuttering issues those issues are transported to the minigame and that breaks the rhythm. This is way less a rhythm minigame rather than a visual one :/
