I thought RPI didn't drop if you beat a bad team.  Did the other teams around us win, or am I misunderstanding that mechanic?

Northeastern beat Maine and North Dakota beat Duluth to raise their RPI above ours.

Since they have all agreed on the system, and I like CHN's presentation better, I'll only post CHN's from now on.

And Q losing to Colgate dropped the bonus points we got for beating them.

I went to CHN to see what the effect would be if Quinnipiac had won.  We would still be 11th and Quinnipiac would 6 instead of 7.  But our RPI actually goes down from .5489 to .5481.  If I am reading it correctly our unmodified RPI falls even more but our bonus is larger.

I wasn't sure what to make of the Q-Gate game RPIwise.  I mean, having played both teams twice, either one winning (or losing) would impact our RPI, right?

RPI is, I think (and a quick search backs this up) just a function of winning percentage + opponents' win percentage + opponents' opponents' win percentage, with each component having a different coefficient (and something in place to keep bad wins from hurting you).  Would it really matter at all which of Q and Gate won, or that we went 1-1 against Q and 0-2 against Gate, as far as RPI is concerned?

It's not a poll, but anyone want to see why shootout wins are stupid, just look at the NCHC standings for the top two teams.

                W L T SW Win % Pts. Overall: W L T Win %
North Dakota 13 7 0 0 .650 39 18 9 3 .650
St. Cloud State 12 5 3 0 .675 39 18 7 5 .683

SCSU gets second because they have 3 ties and ND doesn't. They have the "better record" but lose because they lost the shootouts. They also won twice at ND. Fortunately first place can be determined on the ice, when they play ND at home this weekend.

My impression (not backed by math) is that RPI is all about your record plus your in-conference opponents' out-of-conference play.  In conference, the opponents' record will tend toward 0.500.  OOC record will shift that above or below 0.500.  So if your conference is doing well against other conferences, their OOC won-lost record will be higher and therefore, the overall record will be higher.

Again, not backed by math.  Just my instinct.

I've always worried about the "can't be punished for a win" fudge creating different outcomes strictly based on game order.  Say for instance Yale and Harvard play the same schedule with exactly the same results (their h2hs are ties) except Yale plays UAH (1-31-1) the first game of the season and Harvard plays them the last. Does the fudge factor mean that Harvard will have a better Modified RPI because they aren't allowed to drop, while Yale doesn't get the benefit because, having played UAH first, their proportionately smaller bump is not counted as a "drop"?

(I hate the "can't be 'punished'" epicycle anyway, since it rests on an emotional misperception of "punishment".  I'd much prefer building the impossibility of losing value by winning or gaining value by losing into a continuous function rather than creating an artificial stepwise "floor." )

I would hope that the system would come out the same for both of them.  The only way for that to happen would be to figure out the RPI without UAH in the schedule for both teams, regardless of when they played them.

Pretty sure what it means is that midseason RPI is a work-in-progress. While the games might have a different affect on RPI at the time of the game, they will have the exact same weight in the final result. If you play a team that is 5-0 and they finish the season 5-25, your final RPI treats the game as one against a 5-25 team. Basically you aren't punished for having played UAH in your hypothetical, regardless of when the game was.

This has to be right, right?

I'm pretty sure this is right because the selection committee isn't tracking RPI (or PWR) throughout the season the way we do.  They look at the results after the dust has settled on March 23. Hopefully the various sites that calculate the metrics during the season use the same approach: calculating ratings using the entire season to date to get today's rankng.

The fact that there's a percieved need for a fudge factor simply points to the limits of RPI as a ranking system.  But we've covered that ground many, many times through the years.
