AbigailII: That's filled a gap. I'm not a chess player and only read as much of that Chess Rating link's info as needed to work out how my provisional ratings were being generated, and to note how much more complicated their scheme is than that in backgammon! Now that you mention matches I've reread that page and seen where match length comes into it. Thanks Abigail :-)
