This figure is derived from a triangle on an optical scanning sheet that includes these specifics:
"MCW-APM, Modified Confidence Weighted -Admissible Probability Measurement Copyright 1987 Dr. James Edward Bruno"
Further the scoring system here is reproducible, and was developed by Professor James E. Bruno based on related material Sibley (1973), Brown and Shuford (1973).
Prof. Allen Klinger was introduced to some of this scoring material by Prof. James Bruno. He has used these items in undergraduate and graduate classes. For a UCLA Computer Science Department graduate class involving classification decisions he created an exercise based on the values assigned by Prof. Bruno. The loss matrix here uses those values: elements of the set
{+30, +20, +10, 0, -10, -100}.
