How do the Ratings Work?
The points awarded depend on the
difference in ratings of the two
players. The actual formula is a
complicated mathematical function
but some examples are shown in the table
below. Unlike some
systems there is no upward bias as the loser loses the
same number
of points as the winner gains.
