I would think that there are 20 minute blocks consisting of the usual 5 minutes of presentation, 5 minutes of questions and then the judges have 10 minutes to discuss and prepare for the next group. This is based on what I remember from when I presented in 2009, and what I can remember hearing from our presenters last year, but would make sense as it would be basically impossible to interview teams at 10 minute intervals with no time in between.
