For Sistrix data 7.7% of pages from losers were of an advanced reading level compared to 3.4% for winners.
I used a similar tool that scored complexity (reading level) from 1 to 20. My Pandalized site scored higher (more complex) than most of those that were well-ranking. The free-version I used just looked at about 10 pages.
It's interesting you mention this, again another of many possible factors, but it is something that I noticed a few days ago when I was doing my analyses. It's hard for me to write on a different level. I'm not sure what I can do to improve, but it's something I am looking into.
