Attacking the second argument first, rating in Type One is what a star in Kindergarten is: a vague accolade for something you might or might not have done, which is generally meaningless.
It depends on what direction you wish to go with this, grammatically speaking. You could say "your rating" or "a player's rating," but your lack of a qualifier makes it sound like the verb 'rating.' Alternately, you could say "ratings... are what stars in Kindergarten are:" which would also be correct.
And I believe Smmenen did mean refute.
Anyways, a well done article, and I always like to hear the big shots supporting proxies.
