Do you speed read? What techniques do you use?

I’ve been practicing speed reading to get through my TBR list more quickly. I found 10 Days to Faster Reading by The Princeton Language Institute and Abby Marks-Beale to be quite good, with lots of different techniques for reading faster while retaining comprehension. I went from an average of 350wpm to around 700wpm.

The technique that has been most successful for me was increasing my eye span. Most readers tend to jump from word to word as they read. Increasing your eye span lets you “see” several words with each jump. To see what I mean, try this: using a regular paperback book, try only allowing your eyes to jump from the beginning of the line to the middle to the end of the line (three jumps total), and repeat on the next line. Do this for a while and you’ll find that you’re absorbing more words than you seem to be looking at (your brain fills in the “the’s” “a’s” “of’s” etc., for you). With enough practice, this becomes easier and you comprehend more.

Does anyone else have speed-reading techniques that have been successful for them? Books that have helped them increase their speed? Programs or workbooks?
