So someone from my region went to Atlanta this weekend and when he came back he described what seemed to be a 30 point offset between ratings locally and ratings down there. I won't state whether it was an upward or downward offset, the point isn't to denigrate nor brag about my community. The question is: do communities wind up with significant offsets in ratings as a result of isolation factors? He said that the offset seemed to be significant across the board playing tournament and cash match conditions.
