2019-20 pwr

It is in fact the most important component of the Pairwise. Currently you would have to go all the way down to #40 (Naz) to find a team with a different ranking in the PWR from its rank in the RPI. For all practical purposes the RPI and PWR are identical.

Guys, my bad... What I meant to say is that home (or away) ice does not figure into the PW calculus. I thought that was clear to all.

Clearly, the siting of the NC tournament considers the PW, as well it should.

Two divergent calculi.

Home and away is calculated into the RPI, and for all practical purposes RPI = PWR.

No it isn't. There's no component of home/away in either one.

Here is how the RPI is computed

The Ratings Percentage Index is one tool used to select teams for the national collegiate ice hockey tournament. Factors involved are 1) the team's winning percentage; 2) the average winning percentage of the team's opponents; 3) the average winning percentage of the team's opponents' opponents. These factors are multiplied by 25%, 21%, and 54% respectively and the contribution of each individual game is weighted by a factor of 1.2 for a road win or home loss and 0.8 for a home win or road loss. In addition, a quality wins bonus based on wins against the top 20 teams is added to a team's RPI.

The other point is that the PWR almost always mirrors the RPI - although there are other factors, the RPI and PWR are almost identical. Currently you have to go down to 40th place to find a team with a RPI rank that is different from its PWR rank. There are two ties in the PWR at 10 and 12. The two teams tied for 10th are 10 and 11 in the RPI, and the two teams tied for 12th are 12th and 13th in the RPI.

You of course are absolutely right. I was relying on my faulty memory yet again. Sorry about that.

EDIT: Wasn't the older version of the RPI simply Win %, OP win % x 0.5, and OOP win % x 0.25, with no home/away weighting?

I've forgotten that too.

Two weeks left....different look here with Babson's loss...plus Utica took control of the UCHC.

I can't bring myself to bring Adrian, Hobart and Geneseo together in triad so here's the way I would do it:

Plymouth at Endicott vs. Norwich
Lake Forest at Adrian vs. Geneseo
St. Johns at Eau Claire vs. Hobart
Williams at UNE vs. Utica
 
Re: 2019-20 pwr

If St. Norbert or Marian wins the NCHA, does Lake Forest stay high enough in the PWR to make the tournament? With five teams in the east, you've gotta push Adrian to the east, no?

The previous incarnations of the D-I PWR had things like record against teams under consideration and record in last 20 games as other criteria. Once they were removed and the number of criteria was reduced to three, then RPI ends up the major factor as it is also the tiebreaker. Essentially it counts twice.
 
Re: 2019-20 pwr

Really think Lake Forest’s season is over. 2 losses to Concordia and Trine in the past two weeks doesn’t look good.
 
Re: 2019-20 pwr

They're still at #9 in USCHO's PWR. If Adrian doesn't win the NCHA autobid LF is screwed but they might squeak in with a little help.

Right now, they are the last team in, and the team behind them (Babson) is similarly dead in the water. Upsets could mean that somebody ahead of them currently projected in Pool A might have to use a Pool C slot (Utica, Genny or Adrian losing would probably mean they would fall out off it, or the unlikely scenario that both Norwich and Hobart lose in the NEHC semis.)

For fun, I did it with the Adrian-Hobart-Geneseo triad and got this:

Plymouth @ Endicott vs Norwich
Saint Johns @ Lake Forest vs UW-Eau Claire

Adrian @ Geneseo vs Hobart
Williams @ UNE vs Utica

That triad would be a fun one to watch for sure
 
Re: 2019-20 pwr

Here's a scenario that I wasn't even considering that was pointed out to me by a lurker that is very knowledgeable on the process...

There is nothing set in stone that we have to have four, three-team pods...

The bracket could look like this to adhere to geography constraints and not have to fly a team until the FF...

St. Johns at Lake Forest vs. Eau Claire
Williams at UNE vs. Norwich
Endicott at Geneseo vs. Plymouth at Utica
Adrian at Hobart

#2 vs #4 in a qf? Doubt it

They have done things like that in the past. However, since the Adrian, Genesseo, Hobart triad fits in the 500 mile rule, I would assume they would make use of that to get to a 4 triad arrangement. In any case once the upsets happen, it all will all change

I was trying to remember if they can do that or not... As I stated in the other thread, though, if chalk holds, I think Hobart will drop into the first round game against Endicott and the host of the Geneseo / Adrian game would depend on the bump Adrian could get from beating Lake Forest...
