Good point. We edited the title to something less likely to be construed as proving PG wrong.
All the best to you and fwiw as someone else mentioned, I specifically clicked on this post because i was in "i need a distraction" mode. So I did give your video a shot, but it's hard to listen to 5 minutes of talk.
Just from my perspective I'd like the core of the message to hit me in the face in the first 30 seconds. Then you can drill down into the specifics as time goes on. If you research how newspaper articles are written they use the same concept. They give you the core of the story in the first paragraph. Then as you read more the details and nuances of the article are better articulated.
HTH
