I went to the site you linked to and I took their online demo. I read their test at 538 wpm. I didn't Photoread it. I then took their comprehension test and scored 100%. This put me above a Level 5 on both factors on their chart. The averages for their demo were 227 wpm and 73% comprehension.
From the rest of the site, it looks like they've put together a software program that teaches you to stop subvocalizing and learn to take in two or more words per eyestop. It had an Evelyn Wood and typical speed reading techniques feel. Learning these techniques are great for building efficient regular reading skills, but they pale in comparison to what I've been able to accomplish with Photoreading.
I'm glad they got NASA's stamp of approval, I have to say their program seems like a natural evolution of regular reading. If you want revolutionary, stick to PhotoReading.
