I have no doubt that subconscious works. I just don't understand why soft-focus gets data to your subconscious...
If soft-focus gets data to your subconscious, hard focus should also do it. I just don't see how seeing a "blip" page should be any different from just seeing. If everything you have in front of you goes right to your other-than-conscious mind, I see no use of seeing "blip" pages.
If photofocus really works, photofocus step alone should have great rewards. I mean, they are studying now that it could be almost the same or even better if you don't use preview step. Then, for activation your everyday math classes should do it, supposing you are ussing photofocus to learn maths.
