so I don’t think an algorithm on how much time you spend interacting with a review affects your rating. But really checking everything closely should. I agree that checking both satellite and street view is helpful, and really consider each question. Remember that “I don’t know” is a valid answer, and use it when appropriate. We have 100 skips per 24 hours now, so do skip when you just can’t decide. (Skipping too quickly may trigger a cooldown, but I can’t confirm that.)
