Just because a TD does something doesn't mean that they actually have wide latitude in rules interpretation. It's just they probably haven't been called on it or the "rule" was more of a guideline.
That said, back to the original topic; I looked at the results of the tourney in question and the OP played in the correct section for his provisional rating based on the results of the two games played (I'm pretty sure I have the right tournament).
Where did I get the idea that TD's get wide latitude on rules interpretation?Well,among other things,from observing TD"s exercise wide latitude in rules intrepretation...thats where.
