It's novel because it's not how its done.
It's a big part of the stack rank hate is that people just blindly rank everybody and then adjust compensation that way. Taking more granular detail into account just isn't done.
But also because you're hired to do a job. If you do the criteria of the job then you should get a satisfactory rating. Similar to test taking, if you demonstrate knowledge of the material then you should pass. If you got 99/100 questions right and everybody else got 100/100 then you shouldn't get an F despite you being the worse of the group.
