What is the actual algorithm for determining how many games behind a team is on
a given date? I mean, I can do it in my head, but I'd like to be able to do it
programatically.

I found a thread on Google Answers with some details
(http://answers.google.com/answers/threadview?id=234414). It describes the
formula as:
(1/2) * ((WA - WB) + (LB - LA))

That looks to be spot on to me, especially considering the way MLB.com describes
"Games Behind": 'GB - Games behind, the average of the differences between the
leading team wins and the trailing team wins, and the leading team losses and
trailing team losses'

Can someone confirm this is right? Is this how Baseball Reference does it? And,
if so, what's the answer to the question at the end of the Google Answers
thread: if Team A is 2-0 and Team B is 5-1, who is in first place? do we go by
Games Behind or Winning PCT?

Thanks for the help.
