This is fascinating; thank you. How does an audio book read by the author, such as Anthony Bourdain's Kitchen Confidential, which contains autobiographical information, compare? Is it more like a social situation that you need real time to absorb, or do you prefer it at a higher speed? How does a stage play compare? Do you watch movies sped up?

Also, how does your "baud" vary with your familiarity with the ideas? I can't imagine it's independent. As a ~35 year old programmer with a decade of professional experience and a decade of hobby experience before that, I cracked open SICP for the first time and found almost everything familiar. I had digested the ideas from other sources, so I could read at a "natural" rate. If I had read it as a teenager, it would have been a mindfuck, and I would have taken multiple slow readings to understand. When you talk about numbers like 800, are you talking about writing that challenges you and changes the way you think, or are you talking about stuff you do for a living that is just information you're already primed to accommodate?
