Not every question has a Google answer. Some you’ll have to test yourself.

Some questions have no published answer because they are about your situation, your body, your room, your particular machine. Searching for those returns somebody else’s conditions, and the honest next step is a small test of your own. Knowing which kind of question you are holding saves a great deal of circling.

When searching stops helping, design the smallest check that would tell you something. Change one thing, watch what happens, write it down. Two or three rounds of that beats another hour of reading.
