Yes, being in photofocus, turning the pages with a steady rhythm and saying the chant makes a bid difference.
It helps you stay with photoreading, keeps the conscious mind busy and a steady rhythm and chant helps to keep the mind at the ideal brainwave state.
Changing speed, letting the conscious mind take part and just getting flustered about things like pages sticking together will change the brainwave and make the experience feel bouncy rather than smooth.
The chant and steady rhythm helps to remind yourself to stay with it, missing a page here and there doesn't matter since you can pick it up with superreading and dipping. It's much easier on yourself going through it once or twice smoothly than getting worried that you're doing it wrong and won't be able to activate it later.
