Paul said that Photofocus uses high Theta, NOT Delta. Where did you get Delta from? Of course your not going to believe that Photofocus gets you into Delta, I wouldn't either.
He said Alpha isn't even used. Several posts ago we were all arguing about the best way to get into Alpha but it's not necessary. I always knew that after 15 or so minutes of any activity, if you really like doing it, you're going to effortlessly slip into the "flow" (alpha) state. If you hate the activity there's no way to slip into it without meditative techniques. The simple fact that you have to try to do it indicates you'd rather be doing something else. I will slip into an alpha state after playing tennis but not if I play basketball-because I hate doing it, but someone else can.
