  (1) Results at the Max Merit point; merits are equal to twice the Parameter Weight; no additional merits awarded for performance better than the Max Merit level
(2) Results at the Anchor receive merits equal to the Parameter Weight
(3) Results at the Cap receive zero merits; performance worse than the Cap receives negative merits and the overall test result is a fail regardless of the total merit rating
