I think she and Maddie are both somewhat reticent to go all out. I don't know if they feel pain or discomfort, or simply psychological misgivings. Maddie may also be a bit rusty. But, I think ViVi is also a bit hesitant due to inexperience. I'm not sure that she knows what to do yet. I like what I see of her hands and her coordination. But, she is a bit slower than the videos that I had seen.
