Hi Flamerozzy i think 4 seconds will absorb information. Remember you are not reading here you are superreading. You could liken it to scanning for a particular person's name in the phone book. You don't scan for every name in the phone book you scan for the particular person's name you are trying to locate. Likewise based on what your purpose is you don't read every word in the book you superread for what is related to your purpose.
Some of the problems people get confused with superreading. They do regular reading & think they are superreading. They go way, way too slow. When superreading you should be going so fast that you cannot even subvocalize the words because you are going so fast.
Remember much of what we learn we learn subconsciously. You may not realize it but your mind is picking up many things that you may not be aware of. That is why it is so important to have subsequent superreading passes because you will pick up many things on the subsequent pass that you did not pick up on the first initial pass.
