* RPI-based system (the sum of all ratings averages to 500). * All final scores involving any OAA team are considered. * Margin of victory does not matter. * All games are treated equally, except for: post-season games (weighted double), and losses that raise a rating or wins that lower a rating (weighted to 5% of its full value). *Forfeits are presently included. |
* Teams are mapped to points on a logistic curve (0 is
the center point of the curve). * Only scores where both teams are from the OAA are considered. * Margin of victory matters, but each additional point provides less benefit. * All games are treated equally. *Forfeits are not included. |
