    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?

    Yes, this is basically accurate. The year end ratings incorporate what they call benchmark calculations which are intended to normalize players at each level across all the sections. Players that advance to playoffs become benchmark or "B" rated players so that anyone that played them has a component of their year-end rating given more weight to how they did against the "B" player(s). Thus, if a particular section does really well at Nationals, those players will likely have their ratings go up and then this improvement filters back to those they played at Sectionals and so on. Similarly, a section that does poorly will have those lower ratings filter back down. These are the calculations that are done between the end of Nationals (end of October) and when year-end ratings come up at the end of November.

    However, for a variety of reasons, usually wanting to spread out various league play throughout the year for scheduling and court availability reasons, some sections choose to start a year N league in year N-1, e.g. there are some 2014 leagues that have already started even though it is still 2013. These leagues could simply use each players 2012 year-end rating to determine the level they should play at, but this means a 3.5 that has really improved through 2013 and is going to be bumped up to 4.0 at year-end would get to play as a 3.5 in a 2014 league even though their 2013 year-end rating is 4.0.

    To try to have players play in these early start leagues at the right level, each section establishes an early start rating date at which time the each player's current dynamic rating is used to determine if they should be bumped up or down for an early start league. In our example above, if the 3.5's dynamic rating was high enough, they would be an early start 4.0 and have to play in the 2014 early start league as a 4.0.

    Since early start ratings typically come out in July or later, most league play has been completed and the current dynamic rating is pretty indicative of where they'll end the year and so this is usually pretty fair. Of course, there are some that get bumped up in early start ratings and come back down at year-end, and some that aren't bumped in early start but are at year-end. This is because of additional matches played after the early start cut-off date or the filtering down of the benchmark calculations after Nationals are completed.

    Personally I would like them to change ESR only to bump ups. No bump downs. I have seen plenty of people bumped down for ESR and then tank just enough in the fall and have a C rating at year end. It is one way to keep cycling players who get bumped and then bring them back to a team in 6 months.
