If we determine difficulty rating by people's scores (called statistical method), it will be take so long to get relatively accurate difficulties. I say at least n=5,000-10,000 is required.

I think it should be considered for difficulties as one of factors (along with technical factors like bpms, framers, tps) though, it's just difficult to compare the parameters between songs due to the number of players, release date, etc.
