My point is that there is no set definition of what wins and losses should be recorded. Limiting consideration to just 'top 25' does not help the players who, just as Brian said, beat those who are close to making the list. So top 25 is not valid. Players in competition for the list must have a good majority of both losses and wins recorded.
However all records should be limited to close matches, in which sense I agree with BTZO when he mentions competition. If I get 4 stocked twice in a row, the match is not worth consideration. However if the set went 2-1, and each game went down to the last stock, that would be worth considering, because it is obvious there is a relatively small gap in skill between these players. This shows that simple win-loss records show only who is superior, but not how much. How can this flaw be corrected?
Also, if two players are known to be close in skill, I think that their matches themselves, not just the result, should be considered.
An example: at tournament U, player X beats player Y. At tournament W, player X beats player Y. This evidence lends support to the proposition that player X is better than player Y, and thus should be ranked higher. However the details of the matches are not in consideration. What is the win-loss result? Stocks? These things are necessary in order to accurately related the difference in skill. A point system would help in doing this. Even a simple system, such as one point per remaininf stock for each game; i.e., player X two stocks player Y, then player Y four stocks player X, then player X two stocks player Y. Using a point system, these two players are relatively equal in skill. Without this system, the current considerations (in the case of similar, recurring results) would only show that player X is superior, because he won the set. Thus a point system such as (but not necessarily exactly the same) the one I demonstrated is a more accurate system than the current method used on the master list.
