For whatever reason, the rankings show each team’s entire record (D1 + D2 + D3), but the rating only includes D2 games. That is why PSU’s win percentage is 100% and that number is used in their rating. SoS + AGD + Win% = Rating.
Interesting tidbit: Forfeited games don’t appear to be included in the ratings. GVSU forfeited two earlier against Bradley for using an ineligible player and those aren’t part of their rating (actually forfeited 6, but 3 were against non-D2 teams). If they were included, GVSU would be 5th in the Central, not 3rd. What is kind of funny is that if the Bradley games were actually included (2-2 tie and 5-2 win), GVSU’s rating would also go down. But since they’re just pulled altogether, GVSU gets a higher rating.
