Hi Thomas, I am not quite sure what you are saying here, though I agree, in essence, the scoring system, like most others, is flattening a variety of patient findings into a single term which also then carries a score. The problem is that whilst the ordinal terms are unique, the related values are not and can have duplicates.
So is this a valid ordinal ? ordinal constraint?
