The system has been developed by 1993/94 U.S. Open Finalist Paul Lord.
He has used his knowledge to produce this interactive global squash ranking
system.
Two of the most important aspects of any system is the ease and
speed of use. This system has been developed with that in mind. The
system has no bias towards any player as all players start with a rating
of 0.000. Let me explain
how to get an interactive ranking.
Firstly, both you and your opponent
need to be members of the site. When Player A submits the result (how
to input a result) an automatic
email is sent to Player B containing the result. At this point both players
have the option of deleting it. If Player B confirms
the result an automatic email is returned to Player A explaining that
the result has been confirmed and processed. Both players will then have
new ratings.
It's that simple! The ranking is sorted with the highest player rating
at the top, descending down to the lowest rating. It really is a fabulous
system and without question the most advanced interactive global ranking
system in the world. You can even view your
interactive club/association ranking and print off a hard copy for the
noticeboard. So if you and your squash friends need motivating and
would like to know your playing level, why not register today.
It's great fun and it works!
Below is an explanation of what the numbers mean on the interactive
ranking list:- 
Below is the graph that is used to calculate the player ratings:-

(a)
If players are on the same number of points,
the winning player
gains 1pt and losing player loses 1pt
(b) If higher rating player beats a lower rating player
and there is a rating difference of 2 pts then,
the higher rating player gains 0.259 pts with the lower rating player
losing 0.259 pts
(c) If higher rating player loses to a lower rating
player and there is a rating different of 2 pts then,
the lower rating player gains 1.741 pts and with the higher rating
player losing 1.741 pts.
