Re: Fun With Numbers 2019: PWR, RPI, KRACH, GRaNT, WCHODR, & other assortments of let
Oh. It's because if you take out the tie, the teams aren't well connected because none of the NEWHA have beaten anyone outside the conference. If I make all games involving NEWHA teams exhibitions, the new KRACH values do converge.
Here's the thing though -- you can still calculate RRWP when that happens by separating the teams into groups (i.e. the NEWHA and everyone else). Take out all the games not involving the NEWHA, calculate KRACH for everyone, and assign a 1.000 winning percentage for everyone vs. the NEWHA teams.
...But even when you do that, RRWP still doesn't match up to USCHO's.
I'm so annoyed.
