Well,it's pretty obvious because if you use the rating at the beginning of the game then people would massively resign already messed games and start new games/invites with very low ratings,hence winning/losing a lot more/less points when the game ends.
E.G.:I'm a 1400 and I resign 10 games where I'm a rook or more down.
My rating becomes something ar ...[text shortened]... dered why on [b]all sites the rating used for calculation is the one at the end of the game?[/b]
First off, thats system not sistem.
No I don't see the difference. Lets assume that you resign 10 games where you are a rook or more down (games you will lose anyway). Your rating still plummets down to 1200 and you put for open invites for >1400 which people may or may not accept.
In your system, those games that finish right after your resignations will rate you with a (wait for it) 1200 rating. If using the rating from the start of the game, then you have to wait for those games to end (perhaps months from now) to get the points as a 1200. It is simply a matter of when it happens. Besides, when you blunder the rook away, its probably at a low point in your playing and your rating is now higher thus penalizing you as a 1400 instead of the 1200 you were when you blundered. My only real concer is that if you start a game as a 1200 playing, but by the end you are a 1450, would you just gain the differnce between 1200 and what your rating would be had you played no other games in there, or do they go back and totally recalculate your rating based on the chronology of the start times?
My real problem with your example, is why are you resigning 10 games at a time anyway? That will always cause a large rating drop.
