Talk:Ugo Landini's Pomodoro

The page says that "each set of 4 pomodoros equals an hour of work plus a half hour break". I don't understand which calculation might lead to those numbers. It doesn't make sense either with 25- or 20-min pomodoros, and the breaks don't add up to half an hour either. Should I change that sentence?
