How to improve the Pairwise

Re: How to improve the Pairwise

because a human has to choose what it is?
Well if you used a geometric sequence than you reward beating number 1 a lot and number 2 by a lot less etc. So you end at say 10 with a tiny number and it's still calculable, gets the job done, and makes mookie happy. Kind of like the payoff in a tennis tournament . The winner gets a lot the second guy a good bit but everyone else, not so much. Then you could essentially still end at 20 if you liked with little effect. Except there would be no real advantage to beating number 15.

Re: How to improve the Pairwise

this looks to have that quality bonus in, so bu is higher in rpi due to their wins @ qu and hu, plus home wins vs mich & du at home ooc

Re: How to improve the Pairwise

I am all for adding a 4th, or 5th criteria as long as they are the right ones.
I am against using a team's record in the last X number of games - games in the first part of the season should count as much as the end.
I am against any consideration for missing players/injuries. I know, it sucks…but it's a team sport and every game played adds to your resume.
I am also against anything that introduces an arbitrary cutoff or cliff - so no record against Teams under consideration. That introduces double jeopardy anyway (since it's already in the RPI component).
For the same reason - get rid of the QWB - it is already in the RPI (double jeopardy), and maybe we can replace in a new 4th or 5th comparison.

I think the best criteria to add is something that accounts for Home/Road games. Since conference games are evenly home/road, my first inclination is to just use non-conference road wins as the criteria. The problem is the discrepancy in number of road games by conference/unequal opportunity. I am against using the win pct for those games, as I think its more impressive for someone to go 3-4-1 non-conf on the road than 1-1.

Since that is problematic/probably won't fly, I propose separating the RPI into a separate Home RPI and Road RPI (essentially you have 120 teams instead of 60). That should help account for scheduling quality road games, and help account for various levels of home stadium advantage. The only dilemma with this is how to account for neutral site games: not at all, or count in both the home and road RPI (but for half?). I would count in both the home and road RPI. I'd let the NCAA assign any questionable games pre-season/tournament (e.g if The Big10 tourny happened to be in Milwaukee, it should be designated a home game for Wisconsin and away game for Michigan if playing each other).

Might be a little tougher to go back and look at prior years, as you'd have to track/assign home and away teams; but, I'd love to see this comparison.

I would also alter the RPI formula to put more emphasis on winning (50-20-30), and am for changing the tie-breaker to H2H, followed by Common Opponents, then overall RPI.

So the 4 comparisons would be: Home RPI, Away RPI, H2H, Common Opponents, (Overall RPI only used as 3rd tie breaker if needed, or potentially added as a 5th comparison)

So, there's 1 option if you have time on your hands.

mookie would be on board for a split like this. much like democrats and tax incentives (:D) i think the ncaa has to wield its stick to push inclusive scheduling.

mookie is quite satisfied with bu for in our boys ooc games we visiting union, ylae, quinni, and harvard. for neutral games met nu, bc, & then cornell at msg. and hosted michigan 2x, denver, bucky, and bentley [ok, last 2 teams blew, but...].

other top programs are finally getting out of their home rink as well. even the goofs visited notre dame this year so the days of them playing all their ooc games at home appears to be waning. but it is because of this bonus. if this didn't exist the goofs would continue to invite uconn, merrimack and canisius to the mariucci for the holiday dodge tourney year after year.
 
Re: How to improve the Pairwise

I tend to think mookie is right. Though I don't think it's the QWB that's doing it. They are starting to get harder negotiations from teams. They're demanding return trips because they can now. Minnesota isn't in the same bargaining position they used to be in.
 
Re: How to improve the Pairwise

First, I would like to see LordofBrewtown's proposal (home and road rpi calculations) or at least the rpi portion. I think that would be interesting. Because I don't know, does the current RPI calculation exclude the team in question in both the Oper and OOper?

Second, I agree with mookie and dxmnkd316. The need to encourage scheduling tougher OOC games and especially road games is important. Like dxmnkd31 said, I'm not sure that the QWB is causing it but I think the system rewarding it is important.
 
Re: How to improve the Pairwise

Other thoughts? I'd like to gather a few ideas and incorporate them into the last 3 years of the current system and see how it would have changed the field.

I'd love to see the results if you split the RPI into the 2 componenets as discussed below...eagerly awaiting as I'm far too lazy to do this myself

For all who like splitting RPI into home/road do we keep the weighted game values? How do we deal with neutral sites? I would assume we keep the game weights and count neutral site games as half home half away games?

EDIT: How to deal with QWB? Are we removing that completely? Giving QWB in Road RPI to the victories vs the top 20 teams in Home RPI and vice versa?

Re: How to improve the Pairwise

My suggestions: Scrap QWB completely (it's already part of RPI). Count nuetral games half home, and half road (or just count full for both if that's easier).

QWB really isn't in the RPI calc with it being 25/21/51. Here are the most valuable teams to beat for this season with adjusted RPI rank in paranthesis (before adding QWB):
(1) Quinnipiac
(8) Harvard
(10) Boston University
(4) Providence
(6) Denver
(14) Minnesota-Duluth
(7) Michigan
(2) St. Cloud State
(5) Boston College
(12) Notre Dame
(13) Northeastern
(17) Minnesota
(3) North Dakota
(16) Cornell
(18) Robert Morris
(23) Minnesota State
(11) Yale
(9) Mass.-Lowell
(15) Michigan Tech
(22) Dartmouth

Missing 19, 20, 21

I really do like the idea of giving QWB to road teams getting a positive results against the top 20 home RPI teams...
 
get conferences to reduce number of conference games to have more interconference matchups to allow for better cross conference data...
Other than the WCHA and AHA, the rest play 24 or fewer conference games. If the WCHA were to cut 4 games off their conference slate, it would push more into having to accept more 2-for-1 offers from the Michigan's and 1-for-nones from the North Dakotas & Penn States of the college hockey world. It's already tough enough for the WCHA to fill 6-8 non conference games with equal home and road dates.

Or they could start making deals with eastern schools. UVM, UNH, and Maine have been scheduling each other for OOC, I'm sure they would prefer to play someone from the WCHA.

Which adds the cost of flying to games to an already travel strapped league. But even with a 28 game schedule now, WCHA teams are having more conversations about games with their Eastern brethren.
