[EM] Sport ranking Condorcet method and Condorcet for sports leagues

Hi, just a quickie.

I wonder if you have discussed Condorcet tie-breaking using sport scoring,
like in football (soccer)?
Football scoring obviously rests on the assumption, that only the best
candidates from lower "leagues" (like regional or primary elections) can
candidate for elections, as candidate cloning is an issue here.
The candidates in the top league could also be decided by using proportional
election methods (say 8 candidates elected by STV).
If a candidate beats all other candidates, i.e is the Condorcet winner, then
he/she wins, just like in football and most other sports leagues.
Thus sports scoring is a Condorcet method and could be mentioned on
Wikipedia: http://en.wikipedia.org/wiki/Condorcet_method

Election description:
Each pairwise win gives two (or alternatively three) points.
Each tie gives one point.
Each loss gives zero points.
In case several candidates get the same number of points, then the internal
wins decide.
If all candidates have the same number of internal wins (in the case of
three candidates with same number of points for instance),
then the margins of the number of votes for decide.
If the margins are the same then the quota of the total votes for and
against the candidate decide.
If the quoat is the same, then the winner is the one who had a worse
placement in the lower league.
If the placements in the lower league were the same, then the seniority of
the candidates decide.

This method is not very useful maybe (I guess it fails a lot of criteria),
but it is fun and could draw new crowds to the area of election methods.

An alternative question for further research :o), is how a football league
would look like, if they used Schulze Condorcet.
How would the premier league, NBA or your favourite sports league look like
if Shulze ranking (or some other Condorcet ranking) was used?
Would the football world cup group plays look different with Condorcet
ranking?

A whole world of new oportunities for the application of election methods
opens up :o)

Best regards
