PhotoRead then activate. That's how I pleasure read. Preview is often replaced by postviewing anyway. Other than reading back cover and looking at a few pages to decide if the style and language is the kind I would like to read. Something most people do in a bookshop before they buy the book anyway. That's essentially the preview.
Read elementary style? No. Use the rapid reading technique. Rapid reading with rhythmic perusal. The speed varies throughout the pages of the book. some can be as slow as elementary reading to savor the details and others can be zipping along skittering or even Superreading and dipping. Some sections are just too boring to read slow.
