My darling token,
How sweet of you - I've not heard that name in such a long time! It was my maiden name, you know. Now, of course, I go under my husband's name. Alan.
In order to answer your question, I will quote from my darling Alan's Kibble manual. I found the following note written in the margin in red pen: "Goal difference is, of course, calculated based on all match scores that count as part of the league (full-time and half-time). This is so fuckin' obvious, but I bet one of those idiots ends up asking about it anyway. I'm Kibbling it will be in 2010. I don't know why I bother writing up the rules, I really don't!"
My Dear Alan. He knows how to shout - even in biro!
I've had a look, and this tallies with what he wrote at the bottom of his rules page here:

I hope that clarifies any confusion.
Yours officiously,
- A. Kibble (Mrs.)
