Personally, it seems that increasing the number of displayed words allows me to process the text much faster. For instance, I can comfortably read and (mostly) comprehend at ~400 wpm when 30 words are displayed on screen at a time, while with only 1 word-per-frame I'm struggling to read and have zero comprehension. Comprehension-wise, at the 30 wpf setting, the trouble seems to be when the app splits at sentence boundaries. It's very interesting that this simple tool gives me personal insight into how I visually process texts.
