How to Rate Squash Players
Created 5/5/05. Mru
For the past month I've been trying to improve the method we use to rank our
club players. Before April, we simply summed the box scores of each
player, and bumped the best two players up a box, and dropped the worst two
players down. A few things were missing:
- It was a little hard for people to follow the movements
- It ought to take a little less time for an inaccurately ranked player to
reach his or her proper position
- It would be desirable to assign numeric international ratings
- It would be desirable to rank, on the same list, players who do not wish
to play in the Boxed Ladder. Iit would be desirable to recognize a match
played between any two members, whether they are in the same box, different
boxes, or not even on the Ladder.
I wanted to introduce a system that is:
- Numeric, serving to rank players, in fact give them their international
- Rational and credible, fair and just.
- Comprehensible, although from a cynical administrative point of view, this
is less important than being credible (!)
- Easier to operate. Once a month there is a lot of effort put into
working up the previous month's match results, and removing and adding
players. The latter can't be simplified, but an automated process for
inputting match results and cranking out new ratings would be helpful.
For working up April and May, I used a homegrown formula that is imperfect.
For working up June, I will adopt a formal recognized system, most likely the
USSRA's or Glickman's.
