What I meant is that at points he skips past slides so quick even very fast readers can't absorb every bullet point. I read at ~2-3x the average speed, have lots of domain knowledge and couldn't read fast enough to get every word on every slide. So the pause key is very useful for that even if you know what's coming.

I read at Normal speed but I didn't feel that way when watching. I believe you though, I was just having an XKCD 2501 moment.
