I think we all have a pretty good idea of our own functioning without being told by a list of tables...I know I'm low functioning; I barely leave the house, I don't work, I'm not involved with anyone and have no friends. The latter two being by choice but nonetheless...I think both lists are quite vague and focus more on the extremes - I know 'high functioning' people who self harm and take drugs all while holding down pressured jobs and difficult love lives. Still they're not meant to be diagnostic - best taken with a pinch of salt.
