I am working on that right now, but in the past I multiplied the
point-win of the server in singles by 1.0597, and used an alpha
of 0.60, which results in the server winning 50.9% of the points
in games where the skill is equal.
Likewise, I multiplied the receiving team's pt-win by 1.0540 and
used an alpha of 0.75, which means the server will win 49.0%
of points when skill is equal.
I'd have to get the supporting analysis out to figure out why
I did this. Like I said, I am starting from scratch with the data
now.
