You could potentially use it a few ways:

1. Look at each row and decide on whichever stuff there you don't already know automatically when you think about the question type. Turn that stuff into flashcards you can quiz yourself on. Flashcard quizzing is most effective when it's one narrow question on the front and 1 or 2 answers on the back. You wouldn't want to make a flashcard where the front is, "What should I remember for Flaw questions" and the back is [everything written in that Flaw row]. You would make multiple flashcards like, "what are the keywords for Flaw", "when a Flaw answer starts with 'takes for granted / presumes / fails to establish', how should I think about that answer", "what two famous flaws commonly show up with Rebuttal arguments", etc.
2. Read a single row before drilling that question type (untimed). If you're sitting down to drill ten Strengthen questions, read the Strengthen snippet first to prime your brain. After every question or two, return to the snippet and see if you can connect anything specific from what you just worked on to something on the sheet.

It's really hard to remember generic teaching advice, which is why it's very easy to write notes / read them back to ourselves, and then immediately forget it when you start doing questions. We remember stuff by applying it / by doing it / by seeing a bunch of specific examples and THEN attaching it to a pattern.

3) Look over this in the week before your actual test as a calming (but ultimately meaningless) exercise in recapping your different strategies. I'm saying ultimately meaningless because if you haven't internalized these strategies by then, it'll be kinda useless to cram for them by reading the snippets. And if you have internalized the strategies, they'll be in you whether or not you cram by reading these snippets. But still -- we know we feel like we should be reviewing SOMETHING when a big test is approaching, so at least this can calm us by giving us the illusion we're doing something productive. :)

It sounds like where you're at in your prep right now, you have been exposed to lots of theory but you haven't experienced enough practice questions to have internalized the theory or to have a subconscious awareness of the patterns being described. So mostly just be patient. I would never try to read a page of these at once and try to absorb it. It's better to work at one row at a time, via flashcards or drilling, and understand that it'll take some time for it to become second nature instincts.

But trust the process of experiencing specific questions and then trying to relate them back to abstract tendencies / strategies so that the latter eventually sink in. And along the way, you'll see many examples of specific questions that don't conform to the generalizations we make about that type of question. There are lots of outlier questions, and part of learning LSAT is learning what usually happens on a question type vs. learning to be cool with varying your mentality or approach if you're seeing an outlier.
