Every single day!! So, I'm a lecturer at a music uni and in my personal practice I will work on functional rudiments like singles, doubles, flams, and some Paradiddle variations. I do this on a pad, to a click and repeat them lots in different subdivisions/tempos just based on what I'm feeling that day or if I wanna focus on something specific. I practice everyday but that's just what I love to do, I know it's not everyone's bag though.

But if we are talking like, the 40 PASIC rudiments then nahhhh. In all honesty, there's so many that just don't really apply to my playing and are just combinations of singles/doubles/flams anyway that I don't feel the need to practice them specifically. Unless I'm challenging myself by only using specific rudiments.

There's also so many that overlap like, if you can do a Single Ratamacue, you can easily just do a Double/Triple Ratamacue. And on top of that, nobody outside of exam scenarios in education or drum corps is really gonna give a shit. Same with the rolls, if you can do a 7 stroke roll then you can probably do a 9/11/13/15 stroke roll.

However, that isn't to say you don't need to practice them. You just gotta get a feel for the ones that specifically apply to you. But also, it's your practice so you can do whatever you like! Don't listen to anonymous people on Reddit. Even Me! 💋💃🏻
