The flow of the talk is excellent. He is covering a difficult topic and gives the audience sufficient background to follow the talk.
The font is an appropriate size, but the slides are a touch dense. The graphs are appropriate to the talk and add to the understanding of the material.
Mr. Robinson's presentation is good. Initially, he focuses too much on the screen, glancing up ever few seconds, but soon into his talk he shifts his attention to the audience. His body movements are conservative and yet he makes appropriate use of his hands to give emphasis to his talk. He appropriately uses a pen to point to figures on the overhead.
Nice tie.
He answers the questions appropriately and indicates what is beyond the scope of his talk. Even in that case, he gives enough information to make it clear that he understands the question and gives some appropriate details.
