Cool (and very geeky) read! :-)

I do some front-end developing as well as copy writing and I was wondering, if you could optimize sentences according to this research.

In particular I’m pondering about the optimum ratio between saccades and fixations…:
- Is there a best practice/rule of thumb for how long the saccades should be?
- Are some word/letters used more for fixations than other, or are the fixations “placed” with certain distances between them?

Thank you in advance!
