Interestingly, the WPA rankings do a very poor job of predicting
relative performances in Cardiff.  The correlation between the two is
about .25, which means that only about 6% of the variability in
performance could have been predicted by WPA ranking.

Of course the different round-robin groups are not of equal weight.  I
am doing an NPL-like analysis of the whole tournament.  This will
couple the groups together and will serve to compare the performance of
everyone.

I included the final 64 seeding numbers just for curiosity sake.
Mostly so Sherm can say, "Man, look at that Lee Van go!"

Yes the WPA rankings are based on points earned in WPA sanctioned
events going back I don't know how far.  There are not too many of
those babies, so many players have only a handful of WPA points.  Too
few runs.  Is that the right lingo?  The ranking lists are here-
http://www.wpa-pool.com/rankings/RankingsMen.htm
http://www.wpa-pool.com/rankings/RankingsWomen.htm

My point in all this is to see how fast, if at all, the higher ranked
and unranked players fall off the list.

Not making a statement, this is just for kicks.

OK, local boy issues aside, how in the heck can Corey Dueul get seeded 26th.
Top 20?  Certainly.  Top 10?  Probably.  26????  The bookmakers must be
having a field day twiddling with these numbers.

> NPL?

National Pool League

It's like ELO chess ratings, adapted for pool by Bob Jewett.  It's
widely used in San Francisco and has been implemented in Chicago by Ron
Shepard and is used other places.  The basic idea is that when two
players differ by a factor of two (i.e., the score in a race to 1000
would be 1000 to about 500) they are some fixed number of points apart.
NPL uses 30.  The assumption is that if A beats B 1000-500 and B beats
C 1000-500 that A will beat C 1000 - 250.  It's a logarithmic scale.
It's generally used to handicap matches in local tournaments.

The seeding in the main tournament was entirely based on the
performance in the preliminaries.  The prelims were round robins
in groups of eight.  Matches were races to 5.  It was not hard to
lose two matches in the prelims -- each player played all 7 of his
round-mates.

F.P. Chao, the winner two years ago, failed to get out of the prelims.
