Dr Nettles is a past computer science professor at Penn. He is used to teaching facts and concepts to a room full of sleeping people. They can follow what he says for the most part. His credibility will have to hold up in cross, then we will be on our way. Not sure where Akl fits in yet, cross will probably take up most of the afternoon, so it seems. They have to shoot holes in Nettles, he has demonstrated through testimony and exhibits, the infringement.
