Ya know, the problem seems to be that one person submitted the code
to someone and has been propagated across the internet so now every
site has the same formula with the positive offset. I had hoped that
if had I understood what a future offset is supposed to do, that I
could write something similar (or a null expression) that would allow
me to continue understanding the formula (unfortunatley I am one of
those peeps that needs to understand the formula before I trust any
computer to think for me). Thaniks for the help
