I've been working really hard on this passage, and thought I might post it here since I'm getting really close to bringing it up to tempo. My personal philosophy with this piece is to practice as fast as possible in small chunks and to figure out hand movements as you go. As of now, it's rather inaccurate, but I think that can be figured out once the faster tempo is stable. Just wanted to say, playing fast octaves is much harder than I hoped it would be.
