Say
a
person
starts
to
play
and
gets
some
initial
rating
(
I
didn't
read
the
paper
about
WHR,
so
please
correct
me
about
how
things
are!)
.
That
rating
will
have
some
large
uncertainty,
of
course.
I
play
against
her
and
our
ratings
are
adjusted.
The
*adjustment*
to
my
rating
should
be
given
a
rather
large
uncertainty,
and
the
new
player's
rating
is
also
adjusted
and
her
rating
uncertainty
is
lowered.
Now
let's
say
I
lose
against
the
new
player
and
my
rating
was
decreased
a
little.
The
new
player
now
plays
a
lot
of
games
and
her
rating
increases,
and
her
rating
uncertainty
decreases.
How
can
this
possibly
affect
my
current
rating?
The
new
games
the
player
played
can't
say
anything
about
her
skill
state
in
the
game
that
he
played
against
me.
There
must
clearly
be
a
time
component
in
this
algorithm,
and
I
assume
there
is?
Like
how
long
the
correlation
length
is.
How
do
you
set
these
constants
to
sensible
values?
