Start focusing on a more variety of patterns rather than chord jacks. While the I love It Score is good, you should be at least mid-high 99% on R.A.T.O. This shows a bottle neck of skill in different patterns, where you are more favored in chord jack abilities, while other patterns suffer in acc and most likely control.
I suggest playing lower bpm burst-ey tech patterns (mods optional) to boost pattern reading (focus on 4 star range for now). Additionally keep in mind of your unstable rate, and see if you're hitting to early or late, and adjust accordingly.
Ratio practice can help with solidifying pattern reading as well. focus on 180 - 210 BPM jumpstreams, and aim for low - mid 99. When you're more comfortable with the reading and consistency of these patterns, go for a jumpstream, handstream, and stream charts, and push for 94%.
Overall, don't push chord jack solely, while it is impressive at your skill level to be S ranking such a difficult map, it is just as important and impressive to be a more consistent player.
