I don't have a study to back it up, but in my experience speed-reading multiple words at a time is much better for comprehension compared to the Spritz way of a single word. You can afford to slow down (which helps around blinks) and still have a high effective WPM rate.
I wrote http://velocireaderapp.com specifically to speed-read multiple words better than existing apps (splitting sentences around punctuation the way I prefer). From the emails I get, it seems most users prefer to read multiple words, with 2-3 being the most common length. I should track this.
