Well, I make a video a week and i don't hear any complaints. Anyway, sometimes there's situations that prevent from uploading everyday. In my case I run a collaborative channel and we record about once every two weeks three or four videos. With school and work there's really only time for one video a week to be published. I'm sure that he has a reason for uploading once a week two.
One last thought (sorry for it being so long) He doesn't make the same kinds of videos as you. His (from what I've seen) are scripted informative videos. This includes research writing a script, and editing not only his audio clips but his video surely takes a lot longer than it takes for you to edit a game play video.
Sorry for the rant, but not everyone has to have a once a day upload schedule.
