DMcG: THANK YOU for that descriptive help. Just now I was listening to CBC show "As It Happens" they were interviewing a woman named Jessica Johnson who mentioned that in the absence of tests this year students were graded and placed via the algorithm you mention which led many to experience placements they felt were below their desserts. No one has distributed a description of the algorithm itself, according to the radio story, anyway. Ms. Johnson experienced an episode of major irony because in 2019 she had written a story about a hostile algorithm called "A Band Apart" for which she was awarded a prize named after George Orwell.
