You wouldn't recognise factual errors with traditional reading either. In fact I found they are easier to overlook in traditional reading. What helps you recognise factual errors is your knowledge on a subject and how much you already know about it.
People have experienced the knowing things before they learn PhotoReading. Our peripheral awareness is working all the time. PhotoReading is a system that takes advantage of a natural skill we us non-consciously every day.
That's how we acquired the skill to walk, to talk to feed ourselves. One thing I often ask the student in my class when they ask me how will they know when they got it, Can you remember the day for the first time the shoelaces you tied didn't come undone? That was the day you became an expert at tying shoelaces because you've achieved the ultimate possible in shoelace tying. And sure you have days when they come undone. But you're still an expert. Up unto that day you just did it as best you could and then you became an expert. It's the same as becoming a proficient PhotoReader, you just do it. And it's how we never realise how we came to know things. We just kept doing what it took to get us there.
You won't lose track of the source, just ask yourself which book you need to go back to, to show your source. You'll find it.
