I'd previously written an implementation of the Glicko rating system in
SML. Since I've been trying to learn Haskell, I decided to translate it.
The results are here:

> Hello fellow squashy,
> Sorry I cannot provide any software references for you, but I have had

> Each time I do, I think, "gee, I should just fire up ghci and blah
> blah...", but of course, I get home from squash at "ridiculous o'clock"
> and so ghci is a bit contradictory to my immediate objective - to sleep.
> I'm not sure if you're aware of the "usual" method of scoring local
> competitions, but it is a match of best of 5 (as usual) games and a win
> percentage is calculated by number of games won/total number of games
> For example, suppose I play 3 matches and win 3/0 3/2 and lose 1/3, my
> win percentage is number of games won (3+3+1)/total number of games
> played (3+3+1+0+2+3) == 7/12 == 58.3%
> Many sporting bodies use this number for grading, etc. so it would be
> good have a cumulative number, with graphs, etc. and for comparison to
> others (i.e. for grading).
> A bit early for feature requests I know :) I'll put my hand up as a
> potential volunteer if you decide to pursue it further.
