Quality points & Ranking musings - 2012 Year End

Many poster complaining that WTA should bring back Quality Points.
Here is how Year End Top10 would look using Quality Points:

Code:
	                Ranking Pts  	Quality Pts	Overall Pts	Q Pts % of Overall
 1./(1.) Azarenka	10595		6022		16617		36,24%		
 2./(3.) S.Williams	 9400		6234		15634		39,87%		
 3./(2.) Sharapova	10045		5378		15423		34,87%		  
 4./(4.) Radwanska	 7425		3461		10886		31,79%		
 5./(5.) Kerber	         5550		2853		 8403		33,95%		
 6./(7.) Li Na	         5095		2876		 7971		36,08%	
 7./(6.) Errani	         5100		2533		 7633		33,18%	
 8./(8.) Kvitova	 5085		2044		 7129		28,67%		
 9./(9.) Stosur	         4135		1913		 6048		31,63%		
10./(10.) Wozniacki	 3765		2193		 5958		36,81%	
11./(11.) Bartoli	 3740		1820		 5560		32,73%	



*   Ranking system & Zero pointers are based on 2012 Ranking Rules. 
**  Official WTA ranking in brackets.

Average Quality Points earned per tournament:
Code:
		        Quality Pts	# of Tours	Q pts/Tournament
 1./(3.) S.Williams	6234		13		479,54
 2./(2.) Sharapova	5408		14		386,29  
 3./(1.) Azarenka	6046		17		355,65
 4./(7.) Li Na	        2876		17		169,18
 5./(5.) Kerber 	3408		21		162,29
 6./(4.) Radwanska	3564		22		162,00
 7./(8.) Kvitova	2262		18		125,67
 8./(6.) Errani	        2676		23		116,35
 9./(10.) Wozniacki	2440		23		106,09
10./(9.) Stosur	        2071		23		 94,14
11./(11.) Bartoli	1862		25		 74,48

* All tournament they actually played, not including Mandatory Zero Pointers.

Since many fans would complain that Azarenka played Rome and Montreal just to avoid Zero Pointers
under current system, here are some different scenarios for the Top3:

Azarenka w/o Rome
 -./(1.) Azarenka	6046		16		377,87
Azarenka w/o Rome & Montreal
 -./(1.) Azarenka	6022		15		401,46
S.Williams w/o Cincinnati
 -./(3.) S.Williams	6203		12		516,91
Sharapova w/o Paris
 -./(2.) Sharapova	5378		13		413,69


Quality Points Calculating Method:
Since WTA doesnt have an official up to date quality point system, we have to go back to old ones.
The method is based on the 2005 WTA Ranking System:
http://www.tennisweb.it/Download/WTA...ing_System.pdf
Since points awarded for a slam title went up from 650pts -> 2000pts, which is almost 3 times more,
simply I used the same multiplying for quality points. This is how it looks:
Code:
Quality Points		
Loser's Rank    Non-Slam   Slam
1	        300	   600
2	        225	   450
3	        198	   396
4	        165	   330
5	        150	   300
6-10	        129	   258
11-16	        105	   210
17-25	         69	   138
26-35	         45	    90
36-50	         30	    60
51-75	         24	    48
76-120	         12	    24
121-250	          6	    12
251-500	          3	     6
501 >	          0	     0
