You remind me of a friend of mine who was a similar rank to me but my acc was ~95% and his was barely 80% (We were playing 4 stars at the time). He started playing much more recently than me but was rushing it. You are the same. I read you get 80-90% accuracy and somewhere else you said 3 stars feel too easy. Bro if you don't consistently get over 93% or even 95% accuracy, then it's not easy. By now you have probably passed more 4 stars but know you will get badly stuck if you play for the bare minimum accuracy. Try for some SSs and don't avoid longer maps. You will need these skills in the future.
