I'd say 4-6 hours a day researching my family, and maybe 1-2 hours a day actively researching families in general. Sometimes I just randomly go to a profile on WikiTree and decide to research it because... well, because I can, and that's all the reason I need.
I'd like to throw in another half-hour to hour and a half of studying history during certain time periods as well, because culture affects a lot of stuff. For example, I don't know if my great great grandmother was ever issued a divorce from her husband, but she was writing him off as dead when he was still alive. See: 1900 census she's a widow... when in 1900 her husband is actually alive and well sitting in jail. Turns out it was more acceptable back-in-the-day to be a widow than a divorcee, to the point women would say their ex-husbands were dead before admitting they were divorced.
It's a lot, that's for sure!
