I think throwing up a slop chart like this is incredibly lazy for a company to post. They almost always get something wrong or invent stuff.
If you are having a conversation with someone about a topic and need something kinda quick, and sorta accurate to help explain something in a pinch, slopcharts aren't useless. I've generated a couple based on niche manuals/handbooks. Probably better tools for the job, just the thing I happened to reach for.
