Also, snapping is your friend. If your cursor isn't where the note is, the hitsounds are gonna throw you off when you tap. (I get rekt hard as some high bpm songs have killer OD)
Like Gintoki just said, do some ergo tweaks. Should save your hand in the long run too
Lastly, the build up. Use your Collections grouping to organize the songs you want to improve on.
Then play more.
