If you're kind of easy going with practice ("lazy" in your words) I think the best way to cover the most ground is to master the piece at a slow speed and then let your brain do the heavy lifting of sorting things out with your fingers. In fact, that's the best way for anyone to learn regardless of their commitment level to their instrument. When you're relying on luck to get through parts that means you don't honestly know the music. Practicing and internalizing mistakes can really set you back. That said, it's obvious you aren't lazy. This is just a very challenging piece.
Thanks for the advice haha. I said that just because I don’t really do anything when I’m not practicing 😁 Brain does sort things out every time after practice!
