Does USCF use Glicko?
USCF modified their system to be similar a few years back (where there is a sliding scale to amplify or dampen the rating change for a given match), and now that Glickman (the inventor of Glicko) is on the rating board for the USCF, I imagine they’ll eventually adopt an even more flexible system, like his own.
How is USCF rating calculated?
A player’s rating floor is calculated by subtracting 200 points from the highest attained established rating, and then using the floor just below. For example, if a player’s highest rating was 1941, then subtracting 200 yields 1741, and the floor just below is 1700. Thus the player’s rating cannot go below 1700.
How does the Glicko-2 system work?
Glicko-2 is one such alternative, assigning a Ratings Deviation (RD) around a base number. A player’s Match Making Rank (MMR) then becomes a range (e.g. [1000-2000]), rather than a single number (e.g. 1500). The better the system knows your real rank, the smaller this range will be.
How is Glicko calculated?
The formulas used for the systems can be found on the Glicko website. The RD measures the accuracy of a player’s rating, with one RD being equal to one standard deviation. Twice (exact: 1.96) the RD is added and subtracted from their rating to calculate this range.
