I'm not completely clear on this, but I was told that your year-end rating is some sort of blend of your current dynamic rating and the numbers that come back after nationals finish and the rating info filters back down to local leagues. Is this accurate? Partially correct? Completely wrong? Reason I ask is because some places (Atlanta, for one) have early-start USTA leagues in the fall, and to register for them, you must submit your rating, etc. But until nationals finish and comparative scorings work backward to the local level, your current dynamic rating is still open to change, isn't it?
