Slam Summaries Posted

I have posted the slam summaries for 2013 in the pages over on the right side of the blog and have moved 2012 summaries to the archive pages.  I now have 5 years of data related to the seeded players and also countries represented in slam quarterfinals.

Here's a few comments on this year's data:
-Novak Djokovic beat 14 seeds despite winning just 1 major and notching 24 overall wins.  This means he played only 10 unseeded players, the minimum possible is 8.
-Very quietly Mikhail Youzhny, Andreas Seppi, Ekaterina Makarova, and Carla Suarez Navarro had solid seasons at the majors.  Each reached double digit wins and Makarova notched 4 upsets en route.
-Sloane Stephens was 6 wins better than her seed, which is a huge number.  Tommy Robredo and Suarez Navarro were 4 wins better than their seeds, which is still excellent.
-The number of different men reaching the semis and quarters of majors was up, showing some cracking in the Big 4's dominance, though Murray and Nadal did each miss one major.
-The top five in WTA (Serena, Azarenka, Sharapova, Radwanska, and Li) were fairly consistent throughout the year.
-Three unseeded men reached a major quarterfinal, which is more than usual.  Four unseeded women did the same, which is fairly typical, but Svetlana Kuznetsova did it twice, which takes talent.

A few comments on the country data:

-Each year from 2009 to 2012, 22 different countries were represented in slam quarterfinals.  Then that number dipped all the way to 17 in 2013.
-29 different countries have been represented in slam quarters since 2009.  11 of them have made an appearance at least once in every calendar year:  Belarus, Belgium, France, Great Britain, Italy, Russia, Serbia, Slovakia, Spain, Switzerland, and the United States.
-Chile, Japan, Romania, and Taiwan has appeared in slam quarters during only year during that span.
-Here's a list of the point leaders each year;
'09: Russia/United States - 22
'10: Spain - 18
'11: Serbia - 18
'12: Serbia/Spain - 15
'13: Spain - 22
