To your point, there is a logarithmic difference in grades. A 4.0 takes 10 times the effort of a 3.0, and 100 times the effort of a 2.0.

This whole scheme sounds like going beyond the typical token BS - they want to include race without explicitly indicating it, and they want to conceal the preferential treatment from the students themselves.
It simply won’t work; surrounding them with students using words they don’t understand quickly lets them know they are in WAY over their heads.
