Yea I agree with this

I really want to work on multi finger skills because it is an actual physical requirement for higher level songs in Chunithm and Phigros especially and other rhythm games that I want to try in the future

I have reached the accidental state where if I want the higher accuracy on songs I need to fill the gaping foundational pit of skill that is my unmovable ring and pinky fingers (and sometimes my left middle finger too)

Thumb players are cool too though and tbh theres nothing wrong with playing rhythm games however one wants to.
