Re: Rating Formula Question
I don't understand why
k = 20 + abs(d)/10.
If the rating system is to accurately reflect playing
strength, is a victory with a score difference of ZERO
significant enough to include the "20 +" ? I would think
that you should use a different form of
k = a + abs(d)/b where the maximum value of k is 40, but
with a and b being smaller.
The rationale is that if someone wins by 200 points, is it
"only" worth twice as much as victory by ZERO points ?
Curiously, what is this used to rate?
