I was studying for a cert and needed to review some material faster so I started doing 1.5x and 1.7x up to 2x. What's amazing is how quickly you adapt. The pauses in speech seem to take FOREVER, even at 2x, and when you slow down to 1.5x it seems positively glacial. But you're right, you need to focus. It leaves a lot less time for letting your mind wander. You don't get anything for free. I sometimes watch NFL condensed games and they cut out all the non-play activity so you can watch a game in 40 mins-- which sounds great, but you realize it's 40 mins of intense focus if you want to follow what's going on.
