Paulgeo, you must know that the official rules of chess allow for resignation at any stage of a game, and that resignation is the rated equivalent of a checkmate.
If a player realizes he's in a hopeless position, why should he be penalized for resigning? For depriving his opponent of a fait accompli?
I think the administrators should change the points system for people who resign halfway through a game because they are loosing and they know they can't win. I think they should be penalised heavy like a -50 to their ranking. That's my two bobs worth.
