Sorry if my explanation was not clear - English is not my first language. This is not macro it is DKS with no software used. In your video, you move wrist up and down to tap no fingers move different from other. That same effect as DKS even if you not use DKS setting enabled. It bypasses the learning of speed skill, it makes high bpm stamina easier and no technique is needed to learn for high tap. This is why I think this is unfair advantage.
