The fact is that your Unconscious mind is so Powerful,that it is impossible for you to make it be overloaded.So when it comes to photoreading you might be recommanded to give no thought to such kind of questions. As long as you feel yourself are in a good state, Just keep doing it.But it's better to take a short break between books and Activation Sessions.
