Exactly, this is a good point! There are two factors, the baseline speed of the narrator and the complexity of the topic. Years ago, I attended a Pragmatic Marketing course and the speaker started off by saying he spoke really fast but once you got used to it, you would never be bored or find your mind wandering. I remember that to this day and when I'm speaking in public, I try to keep my pace up. The problem is that the speed up "breaks" you. Once I started listening to podcasts at higher speeds, I stopped being able to listen to slower-paced podcasts at 1.0x without losing focus.
