The priority parameter specifies the relative importance of a given test weighting compared to the other weightings defined in that diagnostic algorithm. More specifically, the priority is the coefficient that the calculation for the current test weighting is multiplied by when it is combined with other weightings during test selection. Although the priority is typically set to a Test limit between 0 and 200, it can be set to negative Test limits and Test limits as large as 2,000,000,000.
