I've been doing this now since 2005, and have been comparing my results with others on the Bracket Matrix website.  I think the results are pretty darn good!

PH Sports Rankings formula is based on 3-2-1 point system - 3 pts for correctly having a team IN, 2 points for having their seed exact, and 1 point for having their seed within 1.

Gary Parrish rankings were similar, but the formula isn't posted anywhere I can find.
