This is a derivative of the Access Scale, using the last 4 elements as a common structure and just changing the first (most common) label to reflect its nature. It has no other representation other than the 5 main measures (no negative, zero, or singular).
Negative Representation? None – penalizing mechanisms are dealt with external to the scale.
Zero Representation? None – penalizing mechanisms having no representation/expression are dealt with external to the scale.
Singular Representation? None – singular mechanisms are dealt with external to the scale.
