Browser-busting proto-KRACH thread

[quote jtwcornell91]Oops, included the wrong image. Fixed now, thanks![/quote] Some day I am going to have to spend the time to understand more fully the inner workings of KRACH. At this time of the year, it is still possible to guess how things should work out. SHU and AIC have each played one game, losing to RPI and Union, respectively. Since RPI has a better RRWP than Union, I would have expected that SHU's RRWP would be better than AIC's, but they are the same. That surprises me.

It's because this particular model is absolutist. Since SHU and AIC have each lost to a team in the big group, and not beaten anybody, the results are explained by making their ratings zero compared to anyone in that group. So in the hyothetical round-robin used to construct the RRWP, they have a .000 expected winning percentage against anyone in that group, along with the teams in the groups above it (whose ratings are infinite compared to RPI, Union, et al). Their expected winning percentage against each other (and other teams not in or above the big group) is undefined, so we set it to .500 to calculate the RRWP.

Thanks, That explains it.

The mega-group is now related to everyone else (until the Ivies start playing):

With UMass and Quinnipiac losing last night, we now have the best RRWP in the land.

Woohoo, we won our first game! ... wait, I already knew that.

P.S. the new forum software does a great job of making this thread title inaccurate.

Do you save these images in any one easy-to-reference place over the course of a season? It would be neat to see an animation of how the KRACH rankings change over the course of a season.

an animation would get pretty boring, pretty soon when everyone is interconnected.

But it would still be interesting to see teams move up and down the rankings. Sort of like this:

If you color-coded the bubbles on a per-team basis, you could get a similar effect with an animation; watch the waves of color move this way and that, pretty!
