When i study, i skitter a lot more than superreading/dipping, since the idea of letting pages and paragraphs go un scanned is just unthought of for me

The key to skittering is to go at a fast pace. I make multiple passes through eveything i read using skittering; building up comprehension through layering. I don't even bother with rapid reading anymore just a waste of my time since i can get enough with skittering.
For me, after i've successfully done the photoreading phase, i notice that as I skitter though the text at a fast pace, meaning/ideas formulate in my mind. If i skip the photoreading phase i wouldn't be able to get the meaning at all. So thats a sign new photoreading may want to look for to measure your success.
