I listened to u and everything u said sunk in into my grey matter. Thank u so much.

Could u do more examples with scenarios like call center response time, Covid testing, Court judgments, Coke bottle filling machines, shaft machining, because it is an extremely interesting subject and useful for almost everyone be it pharmaceutical industry, manufacturing, education, quality assurance in every field.
Thank u so much
