Try focusing first on passing the maps, and then try to get 93% or higher. But mostly you have to focus on consistency while playing ever since the acc is not really important than actually hitting the notes properly.
accuracy by itself is not a very good metric of improvement, focus on your ma and ga (marvelous to perfect ratio and great to miss ratio), try to get at least a 1:2 ma and 1:3-1:4 ga
