Going back to what Guy said in the diary entry called "Week 1", that they would be recording for four weeks, and that he's not replying to questions on his forum for a while, I guess they are working hard to record as much songs as they can during the four weeks the band is going to be there.
Someone made the count, but it looks like this can the the last week, or maybe the next week, so they would be close to the band leaving. Probably Guy would upload a kind of week 2-3 entry, and then another one for the mixing, comping and overdubs, when the band is gone, maybe with some musicians coming in and out to record overdubs, further than the band session.
