I really don't think that sleep amounts help determine bipolar type. Ask your pdoc that question.

There are people without bipolar that do very well with little sleep. I've heard that Donald Trump is one, and there is next to no chance he's bipolar. Maybe some other illness, but not bipolar.

Anyway, when hypo I can get 4 to 5 hours or more depending on how much Seroquel XR I take. When manic I might get 2 hrs or none. Usually if manic, if I go a few days with almost no sleep I usually end up in the hospital.
