Start reading circles as they appear and let the speed at which they appear dictate the speed and the timing for your movements. (kinda like playing HD)
Try to actually stay focused the entire time, if you miss dont get mad(dat 0.5sec of mad), just continue playing or retry right away.
Focus on trying not to miss the entire time, but dont use your brain too much - rather understand smaller chunks of the map.
Use more sight reading - you almost have 2 mechanisms of hitting to the beat.
1st your timing is based on when the circles appear ( sight reading)
2nd your timing is based on the beat of the song ( listening)
Just by following these principles I went from 20k to 10k in about 20 days
