I'm a bit curious about the worth of these educational ratings. I understand broadly speaking a person from a top 20 could well end up earning more than someone from #100. But the difference between #1 and #10 is probably .... negligible. I've noted before there are a few schools where, if you have them on your resume, it produces extra interest, at least initially. I used to review resumes, and it was the case for me as well. If I saw Harvard I probably spent more time on it than if I saw say Missouri. So, there is that aspect for sure. But I didn't differentiate between Harvard and Stanford and Yale and whoever else was considered "elite".
So, I see some value in all this, it's reputational, and may get your foot in the door, but these "precise" rank ordering seems pointless to me.
One could just basket them "elite" and "very good" and "good" ... etc.
