Yeah, sometimes one or both hands overcharge and it can drain stamina, and in my case one side is better for certain patterns and viceversa, my left hand hits trills better while the right one does jacks, if there patterns where these are on the other side it becomes harder
I had so many problems with my hands like during one section of a vibro song my left hand just stopped and it couldn’t move. Another time my right hand began to feel like if someone punched my bone through it with a bat. Lesson learned, always work on your forearm. It’s the most important part of rhythm games
It's always the left pointer finger be lacking when it comes to these kinds of charts . Honestly my whole left hand lags when I play something like this. 🆒💯
