"In ELO-CHESS, only winning and losing matters; the score margin is of no consequence,
which makes it very "politically correct". However it is less accurate in its predictions for
upcoming games than is the PURE POINTS, in which the score margin is the only thing that matters.
PURE POINTS is also known as PREDICTOR, BALLANTINE, RHEINGOLD, WHITE OWL and is the best single PREDICTOR
of future games. The ELO-CHESS will be utilized by the Bowl Championship Series(BCS)."
Of course political correctness has no place in betting football. To say a USC Victory over Oklahoma by a score of 14 to 13 is exactly the same as a win of 63 to 6 would be assinine. If you want to use a number which the author clearly states is less accurate in predicting games (but more politically correct), that is your option.
As far as home field, no matter how little emphasis you want to place on it, it is still valid and a part of sagarin's ratings so it is inaccurate to post a rating that completely excludes HFA. In your second post you included it, which makes more sense to me.
