Obviously the clear problem here is the round robin system (which I think almost everyone can at least agree on now).
It continues to amaze me that everybody did not realise all the problems associated with RR long ago.
After all the year end master had the following problems:
1) Players losing a match and winning (Nalbandian y.e. 2005 and there have been others);
2) Players losing matches to have a favourable draw (too many to mention);
3) Players showing questionable commitment in dead matches (too many to mention);
4) In reflection of retirements the year end master which should have informed everbody was 2005 plus other before. When a player retires it almost makes qualification for the replacement impossible.
