This is a most excellent place for technology news and articles.
I admit already that first point about 10% being more like 20% doesn't look good. I viewed the video, and it seems he may have done that on purpose to facilitate a kind of wordplay between 10 times and 10%, which would be dishonest. Haven't got time to view the rest now, but you made your point.
