Not sure if anyone took notice, however if you go to the team RPI list and then click on prestige it appears to list the prestige in order starting with high A+ all the way down to low D- . Most importantly, it gives you an idea or where you are regarding high and low in a particular letter grade. For instance, if there are 10 A+ and I'm first on the list, I can assume I'm at a high A+, more than likely.
Same thing with free throw grades, Both individual and team.
I'm guessing most vets knew about this, but don't recall it ever being discussed on the forums.
