First question anyone should ask themselves when wondering how many hours to work are: Are you happy? If you're working 4 hours a week and you're happy, then don't change a thing. Being that you said that you find yourself disappointed by your progress, then it's time to do something. I'm not a big fan of working for the sake of work, so I would recommend not increasing your hours, but finding out why you're not achieving the "super-focus" that you think you're missing. Do you "work" yet surf Hacker News half the time? Find out if there is any way to improve your working hours, not add more. That's a recipe for burnout.
