  8. Liquidity: class median 19.91.
  9. Each of the five categories places the model within its peer class, from 0 (the worst of the class) to 10 (the best): a position among comparable models, not a grade. The overall score is the sum of the categories shown that are scored, out of 10 for each (50 when all five are); it is given only when at least 4 of the five are scored, and it can be set against another model's only when both are in the same peer class and scored on the same categories. When accident record and severity cannot be scored because the model has too few records, the other three give a partial score out of 30, labelled as such; it is never set against a full score.
