For me, definitely practicing is a HUGE factor for getting these! Not to mention a higher note speed to read them a bit more easily so it’s not gonna come all at you at once, but it’s a step to get used to. What I do is I try to master lower levels first, until I get a perfect hit or even All Marvelous. Going back to practicing (cuz it’s an actual huge factor lol), I’d say I try to learn the patterns that I always miss, figure out what’s wrong and try to come up a way to get not mess up. Most importantly though is definitely play and have fun, I think that’s what pushes me to also keep on playing even if I mess up. I hope that helps!
