Hi,
In my opinion? Yes. Activate. You'll notice the benefit of photofocus and then the need makes it easier to acquire the skill. You're not seeing the benefit of the PhotoReading step without activation and by now you could have "read" a few books. It's like keeping yourself at level one of a game because you find it easy. Move up the level and you discover the skills you acquired so far are not the only ones but can hinder your adapting to the skills required on the next level of the game. Games imitate learning and your learning experience with PhotoReading will be similar.
