Those are merely your perception of "facts". And, surprise!, you are not the first person to ever determine there are "real, objectively measurable signals that could be used to help moderate". There's an entire legion of workers out there trying to do that.

If you genuinely perceived "real" indicators the market was overlooking, you should implement them and become a billionaire. Go ahead.
