Just some technical details: starting rating of 1200 was used for everyone and the K factor is 30.
Starting rating I can understand but what is the K Factor?
Same article:

I read that K = 800 / (Ne + m) and was still none clearer as to what it meant
Maximum points you can win or loose for a single match.
edit: I completed the calculations for the world cup and will publish later today.
Wow, you have been busy! The World Cup didn't go very well for me so I'm interested to see how the ratings came out...
