Oly's rating got bigger but they were still ranked 7th behind Charm City.Derbytronhttp://allknowingderbytron.blogspot.comnoreply@blogger.comtag:blogger.com,1999:blog-3736639269195513523.post-32741696557186381722009-11-12T09:14:54.974-06:002009-11-12T09:14:54.974-06:00@Grand Poobah
It's a problem that's unfix...@Grand Poobah<br /><br />It's a problem that's unfixable in computerized rankings, in my opinion. Anytime, I see a team playing better or worse than previously in the seasson, should I delete all their previous games? Obviously, that can't be a solution, it brings in a human element and takes away data. I could weight more recent games but I also think that is a mistake. After Charm City beat Philly, if that game was weighted higher than the rest, Charm probably would have been ranked #1 and Philly would have been out of the Top 10. Obviously, that's a bigger impact and more of an egregious error than where we currently sit.<br /><br />In reality, this is a very small problem that rarely occurs and it's currently only affecting two teams. Yes, Rocky Mountain is probably ranked too low and Pikes Peak too high, but we also have to remember that we're basing this completely on one weekend. It could be argued that Rocky Mountain had a great advantage with having new players that no one had seen play with RM before, and thus they implemented different strategies that no one could have prepared for. You could also argue that Pikes Peak was still getting their feet under them and hadn't found the best uses for the players that would have to step up in the absence of the three players that left. If Westerns were played again today, it could be a completely different outcome.<br /><br /><br />Teams don't necessarily move down when they're beat. If a team is expected to lose to Oly by 100 points (based on where each team is ranked) and they lose by 50, Oly would move down and the other team would move up.<br /><br />Maybe Oly doesn't have the 7th best travel team in the country but the one game against Rocky Mountain where RM should have maybe had a higher rating, maybe .04ish higher, really wouldn't affect Oly's rating that much. Remember, it was only 1 game out of 8.Derbytronhttp://allknowingderbytron.blogspot.comnoreply@blogger.comtag:blogger.com,1999:blog-3736639269195513523.post-24380083777338820532009-11-12T08:45:05.414-06:002009-11-12T08:45:05.414-06:00@Andrew Ross and Grand Poobah

It also has problems with adjusting to sudden changes in a team's capabilities.<br /><br />In other words, your system still thinks that Denver is better than Oly and Rocky Mountain Rollergirls. In fact, it still thinks that they're a LOT better than RMRG. And for that matter it still thinks that Pikes Peak could beat ACDG.<br /><br />And like FTS misranked teams like them spread the problem around. Every time Oly steamrollers another team, they get adjusted upwards (correcting the problem somewhat).<br /><br />However, they also give a similar downward momentum to whomever they've beaten. When the teams that lose those bouts were probably performing as well as could be expected. Meaning Denver is perhaps a bit better than you've been seeing them?<br /><br />Likewise, a bunch of teams at Western Regionals that lost to RMRG probably look a fair bit worse than they actually were.<br /><br />I'm not saying Oly can beat Gotham (I'm also not saying they can't). What I'm saying is that I have some serious doubt that they have the seventh best travel team in the country.Grand Poobahhttp://www.derbynewsnetwork.comnoreply@blogger.comtag:blogger.com,1999:blog-3736639269195513523.post-1003821867416188142009-11-12T01:06:03.658-06:002009-11-12T01:06:03.658-06:00What Andrew said.
