It's the same. Even Mr berg points out that an expert reader speeds up and slows down according to the text. With Mr Bergs course my best reading speed was 800 wpm. Now im rapid reading an average of 1800wpm without having had to do the daily 1 hour drills.
In any most cases I don't even need rapid reading, using superreading and dipping is all that is required for many books. I just use rapid reading on books I want more out of or just want to read for the pleasure of reading.
There is no need to add extra work to improving your reading speed. When you follow the steps of the PhotoReading system you'll find that your reading speed increases naturally. To get the hang of photoreading I dropped everything I had learnt about reading. Including speed reading and just worked with the methods.
