One week per side and one layout per week was my original goal. I didn't figure I'd have enough to do two sides per week. I guess some weeks I have more and can use more, but I haven't broken to that level yet!
I don't know if I've done all the layouts either, but I'm trying (at this point) not to get overwhelmed. For me it's about the story - through pictures or words - of the year. Life doesn't happen in neat little blocks of time!
