Tim Ferriss's method focuses a lot on eye movement. I question the decision of lines/keeping lines over making the words move instead of your eyes. On the web - we can move text to where our eyes are, instead of focusing on imaginary lines to aid in speed reading.

I use something similar to Squirt [0], unfortunately I forgot the name as I failed to properly name the bookmarklet. Unfortunately Squirt is a little buggy and doesn't strip out connecting/useless words (just, basically, a, etc.) but it gives a good idea of what I'm talking about.

I typically have it set to 850wpm~ which is good enough for comprehension so long as the material is within my vocabulary. If it doesn't parse well (punctuation like parenthesis often breaks the parsing) or the vocab isn't in my reach - I drop it down to 450-550wpm.

Edit:

Spritz is another speed-reading bookmarklet that I recommend over Squirt, as the parsing is better:
