20 times 3 minutes is 60 minutes Conscious comprehsion = zero; especially for a beginner who has not yet learned to know their internal message for go or no go.

PhotoRead once activate in 3 20 minute passes = 63 minutes comprehension level for a beginner similar to having read half the book.

You can begin activating 20 minutes after PhotoReading and if you leave it over night you have given your mind more time to process the information.

PhotoReading... once is usually enough.
