What is a recommended time to practice the speed reading exercises?
My recommendation is 10 minutes of practicing (number finds, saying “a-e-i-o-u”, etc.), don’t place an emphasis on comprehension during this time. Then read for 20-50 minutes as you normally would, focusing on comprehension and adapting your new skills to your reading time. Practice your exercises for another 5 minutes if you notice yourself slipping back into your old habits. This may be frequent in the beginning, but it will lessen over time.
