Background of OACS

Some years ago it occurred to me how inadequate the existing means of ranking Odyssey episodes were. They were typically inflated, with even episodes that were almost universally considered to be among the worst in Odyssey history regularly getting at least 2 or 3 stars, or especially high percentages on the AIOWiki rating system (which still has a lot of overrated episodes to this day, with the exception of any new episodes, which are by default not 'chic' no matter what the episode is like).

To the end of fixing this situation, then, I had the idea to use a relative rating system, not unlike the Kittenwar page or other 'versus' sites. This protects episodes against rating inflation or deflation (the latter being a distinct possibility given that so much of the AIO community 'old guard' these days don't actually like the show anymore) by comparing them only against each other, rather than someone's abstracted notions of what an episode ought to be.

It also has the side benefit of limiting the amount of information that must be processed at a time. Ranking some or many episodes against each other is hard. Remembering the ratings of every episode ever so that you can conclude an episode should be 86% is hard. Deciding whether one episode is better than another, however, is not hard. To an extent, you do it every time you decide what to listen to.

So, the resulting rating system is lightweight, easy to use to make ratings without a mental overload from processing lots of information at once, quick, and can be done in short spurts or over long periods of time.

Its one obvious disadvantage is that it does not quickly produce an accurate rating. It takes a long period of time with many matches between episodes to get a ranking that is statistically significant. While this is eventually self-correcting, it is still an imperfection. As of yet I don't have an obvious solution to address this, but it is something that I hope to be able to help with in some way in the future.

Understanding the Statistics

Each episode has several relevant categories to understanding its degree of success in the rating system:

Using the Stats Page

Click on the links at the top of each category to sort the table by that category. The search engine is very sensitive and picks up text from any category (not just the name of the episode or album), so it can be used for more than finding individual episodes.

Fixing Common Problems

Sometimes the site and theme are updated, and the new CSS file might not always be rolled out to your computer. If the site is uglier than it usually is, refresh the page.
