A Quick Question About Ratings???

[Devine_Limits]

I was just wondering, what would be a correct calculation for the rating system???

For Example :::


What makes A::

F - 0 - 10
E - 10 - 20
D - 20 - 30
C - 30 - 40
C+ - 40 - 50
B- - 50 - 60
B - 60 - 70
B+ - 70 - 80
A - 80 - 90
A+ - 90 - 100

I know that is probably wrong, thats why i wanna find out the correct ratings.
Because I plan on buying TEW 2010 but i also plan on making RLM's.
