Assuming that the homework is "practice" and not "instruction". A good bit of my older kid's homework is continuation of the instruction at home without the benefit of the teacher. Not that I fully blame the teacher for this, I blame the district for it as much, if not more. But to continue the metaphor, I would expect a child receiving five one-hour lessons a week on piano to be proficient enough to show they have received lessons within a decent amount of time. Without extra practice. But what's the criteria to consider it a success? What amount of time? Do we consider whether the child has a natural talent for it in the equation? Personally, I don't think it's a good metaphor.
