when you photoread a certain text, do you just photoread it ONCE, and then wait 30 minutes or so and then activate, and/or keep activating by layers. or do you photoread in layers, then activate in layers? would photoreading in layers be more effective?

thanks

Edit: i'm taking home course atm, the one with the 8 CDs. however i've been skipping through some of them and haven't heard anything about the steps of photoreading, like super reading, dipping etc. on the products section of this website, it says what is explained in what but i haven't heard anything so far, through skimming. also i'm on CD 2 atm, and all i heard was about "Image Streaming". is this all really necessary?

also is it possible to PhotoRead properly w/o taking this 8 CD course?

thanks
