I selected 41-50, though like others I'm more functional in some areas than others. I maintain relationships MUCH better than I function in a work environment. I can only work from home because the stress of going out to a job every day overwhelms me even on meds, but I'm engaged and have a handful of friends I've maintained relationships with through many episodes, as well as being fairly good at making new social relationships and maintaining relationships within my family.
I probably function at a 65-70 average when I'm not having episodes. If I could just pull the work thing together I'd be very high-functioning, but, yeah, I haven't managed that.
