NOTICE REGARDING THE USCF RATINGS SUPPLEMENT   The USCF publishes official ratings updates (known as "ratings supplements") on a monthly basis. These supplements normally reflect tournament results received by the first Friday of the previous month. For example, the November 2010 supplement should reflect results received by October 1, 2010. In tournaments, player's ratings are used to determine pairing order, eligibility for some of the prizes, and for correct section placement. In order to utilize the most up-to-date official information, it will be the policy of the NSCF to attempt to use, at pre-entry time, the following month's supplement for any tournament that is run on the final weekend of any month, assuming availability for download. In addition, we may sometimes use the latest known weekly rating of a player (as posted at uschess.org/msa) to insure proper section placement. See a detailed explanation at The Rating to Use.
