As
the European roller derby scene grows and the skill levels of the top
teams increase, the WFTDA rankings are sure to become a more and more
important indicator, especially as success in those rankings will be
a ticket to a whole new level of game play i.e. the championship
games.
Roller
derby as a sport is going through a period of metamorphosis during
which both international organisations as well as national
associations are trying to find their own place. Even the WFTDA rules
are in competition with other roller derby rule sets but at least we
can say that the teams that play under the WFTDA or MRDA rules have
one thing in common: the rules. Each derby team has a different
season and different culture. Some leagues play interleague bouts
whereas others organize big tournaments or competitive tours. One
thing we know for sure is that everyone wants to be the best. But how
do we measure this?
Considering
that not all leagues and teams, that play under the WFTDA and MRDA
rules, are members of the international governing body and that mixed
teams don’t even have the option of becoming members, it is
difficult to determine how to rank these teams and especially how to
compare the skill levels of the European all-star teams with their
American counterparts. The answer is to develop a ranking-system
based on bouts that the teams play. But because bouts are still
arranged only occasionally and rather irregularly, the teams don’t
necessarily fully know their opponents level and thus bouts may end
up being pretty unequal matched. Therefore, the ranking system can’t
just be based on the score difference. It is also important that the
rankings also support the teams in picking their opponents. As a
result, various ranking-lists have sprung up based on different
formulas and it seems each one of them has something to offer. Some
listings don’t compare the number of bouts won to the number of
bouts played whereas some have split teams into different divisions,
which don’t really reflect reality. At the moment, it seems a lot
of people are talking about WFTDA’s new, division-based ranking
system that also affects the seeding of WFTDA member leagues i.e. how
the tournament places in the championships are distributed. As a
result of the teams being split into different divisions, many teams
are unwilling to play any opponents ranked lower than them because a
surprise victory would mean a big drop in rankings. For example, this
means that it doesn’t make sense for the London Rollergirls’
all-star team to play at all in Europe because LRG is ranked far
above any other European leagues. So why have such a ranking system?
Mathematics
instead of geography
The
teams in the WFTDA championships have so far been selected on the
basis of the leagues’ geographical location and playoff tournaments
in North America. Until now, the playoffs regions were Eastern USA,
Western USA as well as North
Central and South Central USA and, at the WFTDA tournament in each
region, 10 teams competed for three places at the championships,
which are arranged every autumn. The regional split will still remain
as there aren’t sufficiently many European member leagues competing
at the top level to justify setting up a separate Europe-region. The
teams from outside USA will compete in the region that they are
geographically closest to, for example the European teams would
belong in the Eastern region. After the geographical split was set up
and up until 2013, WFTDA used voting-based rankings, which took into
account the bouts each team played over the course of the year, to
determine the placing of teams within a particular region. During
2013, the fully mathematical Competitive Division System stepped into
play with the hopes of some day getting totally rid of the
geography-based system.
