Talk:Area compatibility factor

It needs to be made clear what is the numerator and what is the denominator of the function $F$. It's easy to assume the top fraction is the numerator and the bottom fraction is the denominator, however, it is still an assumption. Plus it doesn't help that I don't have a clue what the function does... Deskana 22:56, 26 October 2005 (UTC)

I've added brackets but I don't know why it is necessary...
