No, hardly anyone could go wrong doing any technique in photoreading unless they alter the sequence.

Newbies often get confused over super reading because it is not explained in the course nicely. You have to use it for many materials or alter its pattern to get it to work. technically, super reading is purposeful skimming. it is as simple as that. now, if you super read every page, then it will take you 2-3 hours to get through a book. but that is not required because the system wants you to be selective for a text you are exploring and be questioning about it.
it is like, your friend is holding a book in his hand and you want to know what is there in the book. but he is not allowing you to read it. so what will you do? you will ask him questions. the same approach is with activation.

And yes, dont think activation is just about finding answers to your questions. many unusual things happen when you start activating. You may feel new information flooded in your memory out of nowhere! this is amazing experience. Like, you activating for the description of a pizza and you suddenly getting all in depth knowledge about pizza given in the book. This is activation! Look for such flooding of information when you activate. Otherwise we feel we have activated a book when we get some structure about the book. This is not the actual benefit. you can get the structure by just previewing!

JUST keep on doing it, you will never be worried about where to dip. initially you will feel to dip every paragraph. dip into it. no problem. but see if you get all the information you are looking for. if not, then dip again. what is essential is, to keep on doing it. after a few days, when you will start activating, you will feel as if you have read the book word for word thrice! it feels so easy to activate books! just keep on doing it.
