Re: Buffalo Bulls varsity men's ice hockey?
I am sure you have much more expertise on PWR than I; however, taking a quick look at the Primer on CHN, I do not see much reference to whether the opponent is in-conference or non-conference. Maybe I would have to drill deeper on that for an explanation. However, it is not just RIT v AIC for one game. It is three games against AIC ... and three against SHU ... three against UConn ... three against Bentley ... etc. Essentially, most of the schedule eaten up against weak competition with only seven NC games to build a better PWR in non-conference performance.
Well, to be completely clear, I'm not saying playing in a weaker conference* has no negative impact on a team's RPI, because that's a ludicrous assertion. It often does, but it's more so the case that it has less of a downward pull than one would assume.
There's no specific part of the system that says "non-conference games are worth more", but it is more of an emergent property of the way college hockey teams schedule and organize themselves.
Givens:
1) We have insular scheduling groups (i.e. conferences), and do not even attempt a true round robin (or even a nationwide schedule balanced by region/conference).
2) Within an insular scheduling group, the aggregate record of all teams playing within that group is .500. For every team that wins, another must lose.
Conclusions:
1) The only way to statistically define strength on a nationwide scale between insular scheduling groups is by looking at the results of games between those groups.
2) Those games, therefore, have more of an impact on statistical readings relative to a team's winning percentage than those played within their scheduling groups. Example: UVM's appearance in the NCAA tournament in 2008. UVM was 8th place within Hockey East, but because they had a strong NC schedule that they performed well against, their PWR factors were bumped up to the point where they were able to 'leapfrog' teams who played better in their own league and get an at-large bid.
*Which, in and of itself, is defined statistically as "the aggregate non-conference record of all teams in the league is on the lower side of .500".
