What I noticed using this to read a couple Ars Technica articles was it worked really well for short words. But, if a longer complicated word appeared, at say 600 wpm, I would miss it. It seems like an adaptive algorithm based on word length would improve the speed even more allowing it to go faster on short common words and slow down on longer unusual words.
Also, there is bug that sometimes causes two words to appear at once. Sometimes they are overlapping vertically which is basically impossible to read. Try reading http://pragdave.me/blog/2014/03/04/time-to-kill-agile/ to see what I mean.
