You seem to be about on par with where you should be. Sorry if this isn't the boost up or tear down you were looking for.
Some tips to improve:
1) Learn more about the game
1|2
2) Be sure to use the "spread" playstyle
3) Focus your eyes not on the receptors, but somewhere in the middle of the play area.
4) Develop muscle memory by playing similar songs (style and difficulty)
5) Be sure to increase your speedmod periodically as it can boost your accuracy and reading ability. There is a certain point where you will no longer feel the need to up your speed mod, and that is unique to you, and that is fine.
6) If you find yourself running out of songs in your comfort zone and slightly above (which is the recommended zone you should play in ), revisit some of your favorite songs with an increased rate mod (speeding up the music and notes to make the song harder).
7) Find someone to compete with, invite a friend.
