I wish they'd give you more than 2x speed in the web player. Lots of videos seem to talk extra slowly to drag things out to the point 2x speed sounds like normal conversational speed.
It’s hard to talk that slow and still be able to keep the viewers attentive to the content. I often put on 1.5 or 1.75x as most since I’m not a natural English speaker, though that may be different for born speakers.
