I was in a ~12 person group conversation this past weekend and most people genuinely thought the continued reporting of the rolling average was ~10% compounding monthly. I hate being a "know it all" type in casual social situations but it was so disconnected from reality that I had to put on my mansplaining hat and give everyone a lesson on how these things work. Unfortunately, the media is to blame for this and their motives are aligned with the misinformation. They do a horrible job with almost all numerical reporting.
