This is a bit of an old thread, so I hope OP has found his answers among the many useful comments and doesn’t mind if I go a bit off-topic. I just want to pick up on the “sleep on it” suggestion. It did not happen much during B2B or I don’t remember it, but now that I’m learning full songs and play over (more complex) recorded music, it happens quite often that my brain picks up a few key moments or passages and repeats them while falling asleep or sort of “in between” dreams. For sure part of that it’s practicing late in the evening, but has anybody experienced something similar?
Also on the original topic: if the same/similar mistake happens quite often, I would take the sequence that causes trouble and repeat it at much lower speed, even in 2 or 3 notes sub-groups, until the fingers just know what to do at regular speed, possibly before the mistakes becomes ingrained.
