It's a good point to bear in mind. 

Even in (seemingly) simple cases like alt text, an image can have alt text that may or may not have " equivalent purpose". 

Currently that would mean different testers have to choose between pass and fail, which makes the end result look wildly different.

With categories / rating / percentages within guidelines, the difference between category 2 & 3 out of 4 (or between 50% and 60%) does not look as different. 

Done well, the effect of *accounting* for subjectivity (that will always be present) is that it smooths out the results, and you get a closer agreement between testers overall.

Kind regards,
