@er1n it helps! I've been doing them a bunch recently as I get back into playing and I've noticed a difference. plus idk, they're slightly more interesting than scales/etc, but they definitely don't require the same focus as working on pieces. I can kind of zone out and grind through them, it's great when I'm feeling agitated

I can take a picture of a couple if you want an idea of what they look like, just lmk
