so after taking that stream speed test java thingy, I decided to test my fingers for single tapping bpm speed. my middle finger ( z ) ) , the one i currently single tap with scored 30 bpm lower than my index ( x ) ... so i decided to switch my single tapping to my index. since i'm a new player and only playing pleb 3* maps i think it's not too late to do this. my acc in single tap maps has improved so much but apparently i cannot start/end streams triples without my fingers going sex mode with each other and i miss. is there any hand exercise i can do to make my index the boss or i just have to rebuild muscle memory all over again?
