There's been some talk and suggestions regarding the rating system recently(separate rating for clans etc).
Personally.I don't care about my rating but I know lots of players do.
An example of why the system isn't perfect or indeed a reliable guide to a players ability:-
I don't time players out,I know it's in the rules but I prefer to play games to their conclusion win or lose unless my situation is hopeless when I will resign.
I have been playing a chap who regularly failed to move within the time limit.
A whole lot of players must have timed him out,because his rating plummeted to 800 or something.
I then lost the game so my rating plummeted also.
Ok-so this doesn't bother me but gives a false indication.
If there was a way to separate time out losses from the current rating system it would make it more accurate.
