Why would you play the tournament if you don't agree with how the promoter does his business?It usually goes like this, I enter as a B+ player because that is what I am then see someone else as a B that should be an A, I tell them "this guy is not a B player because of this and than reasons" the reply is "well he is a B player here". I give up a spot to a guy that shoots better than me because when they say B they actually mean "our local definition of a B" that is an A using the scale logically. It's like going to a fabric store, ordering a yard of cloth, getting two feet and being told that "our local yard is two feet".
What is their rational for rating you the same as this other player?
If you know that is how they rate a higher player why not sign up as a B?
