The basis of Spritz concept is that much of the time spend reading is “wasted” on moving your eyes from side to side, from one word to the next. By flashing the words quickly, one after the other, all in the same place, eye movement is reduced almost to zero. All that’s left is the time you take to process the word before the next one appears.
A college-level reader tends to read at between 200 and 400 a minute, according to HuffPost. Using Spritz, if you can handle 1,000 words per minute, you’d only need 77 minutes to complete the first Harry Potter book (which is 223 pages long).
