How does the demerits system work?
Many people are used to scores based on subtracting the demerit points from 100, as when they had 25 demerits reported as “Scored a seventy-five.” The current method does not subtract from any arbitrary number; instead we just report the number of points “demerited.” This is done because some establishments, e.g., bars, would have several items that would not apply and they would therefore get “free” points added to their scores when comparing them to a full-service establishment.
