my prev tags :D - #my apologies its a question no one asked but i am full to overflowing with information on this topic #now if you want to hear about WFTDA Ranking Points as in you can lose against a better team but beat the EXPECTED points ratio #and have outperformed how you were Expected to do and thus increase in Ranking Points #because as a all volunteer sport theres never a Everyone Plays Everyone so that s just how they do
#> prev tags that's all so interesting thank you! #i really don't know much about wftda specifically so it's really cool to hear more specifically how the game works #roller derby
yes! Small leagues [oh yeah... a small area that has 1 or more roller derby teams that practice together are generally called "leagues" which is kind of weird but that's the vernacular] often just play among themselves (if they have 2+ teams), or play neighboring leagues for funsies,
but larger leagues usually belong to a bigger governing body, like WFTDA for example, which has a standard rules set and lots of other stuff. WFTDA also includes math stuff that creates Rankings.
Rankings are both for things that would be recognizable in other sports ("who's the best in the region?" / "playoffs among best-in-region" / "bigger playoffs eventually determine best-in-world", etc)
and for practical concerns in a DIY / all-volunteer sport, for playing nearby teams. It generally lets you know which teams are of generally similar skill level to reduce the chances you get complete blowouts.
Or if it's going to be a really un-even matchup you can have a sense of HOW uneven and the generally expected point differential - for a simple example, "they're better they're predicted to have twice as many points as us - so if their final score was 100 and our final score is bigger than 50, we did better than expected"
And of course the good thing is Rankings are adjusted after each bout, so it's re-assessing each team for better predictions. (In the above example, if the 'better' team got 100 and the other team got 75, the better team would lose ranking points and the other team would gain ranking points.
anyway lots of math and lots of nerdery, all to the end of "how do you arrange competitive games with an all-volunteer massively distributed sport, where there's not budget for the standard Everyone Plays Everyone X Times kind of things".
I'm sure there's lots of places to look up details on how it all works but I think that's a quick "what is ranking? Why is ranking?" as I understand it.
