The more games you play, the more accurate it will become...up to a point. One's rating will never be 100% accurate however, so don't get too attached to it. 😏
I have just received my first ever chess rating, which I'm quite proud about in one way but on the other hand its left me a little confused!
I know this as probably been asked a fair few times before but how come my rating has gone down even when I've won?
Also how many game would it take to get an accurate rating & how does this rating compare to over the board ratings?
Cheers 'a fairly proud' Jay

Until you complete 20 games, you will have a provisional rating. This rating is calculated as the average of all the games you have played. Each game is scored as being your opponent's rating (for a draw), your opponent's rating plus 400 (for a win), or your opponent's rating minus 400 (for a loss). If your opponent is also on a provisional rating, then the ...[text shortened]... nd you get 1489.
1519 + 1596 + 1489 = 4604
4604/3 = 1535 (your rating after three games)

Just to add to this topic,
Would it be worth while for a highly rated player to play a low rated player as far as gaining points go? What is the biggest difference needed for the higher rated player to get zero or even minus points?
ie; would Weyerstrass for example gain anything in playing & beating me?
I hope this question makes sense?

eg. A player with a 2000 rating plays 100 games with players ranked players ranked 1200. Each game he wins awards him only 1 point, put a loss in any of the games costs him 32 points and a draw would cost him 16.
So while it looks pretty decent for padding your rating because you should win 99% of the games against someone 800 points lower than you, one careless move could easily cost you a lot more points than you are farming by winning most opf the other games.
Note: The 1 point minimum guarantee only applies once you are no longer a provisionally rated player. It also guarantees that you will lose at least 1 point for a loss.
