It's flagrantly misleading to claim that "being black is worth [x]" when this scale is dated and explicitly prohibited from use after Gratz v. Bollinger (2003).

See here for UMich's 16 year old explanation of this scale:

Do you have any data suggesting anything of the sort is still in use?

Colleges are secretive, so we need to make do with what little data the court forced them to reveal. I know of no data more current than this. Do you have any evidence things have changed?

How can you take something as useful evidence when it has been explicitly prohibited from use?

Unless public colleges are secretly flying in the face of a Supreme Court ruling, your assertion that "being black is worth +1.0 on GPA, whereas underrepresented state is +0.1 and underrepresented county in Michigan is +0.3," is unproven by the evidence you provided.

Had you said "was," and explained that you don't believe things have changed, that would have been far more intellectually honest.
