your china emperor story only suggests that the parent post's averaging scoring scheme consist of reviewers who dream about a 'test-taker' and then give a score (repeat as many as test takers there is) ... if they have access to takers' answers and keys, then averaging could be done much more objectively

the china emperor: that's maybe because there's no photograph of the emperor circulating. if there is, one can make comparison to eyes, age, coin, ground-legal-measure etc and clean out the outlier data. averaging the rest can give good enough estimate but not super accurate.
