Ratings here are a mystery, why should it go out to decimel points? A very simple way would be: scores within 200 pts, 6 pts. scores with in 400 points 4 pts and etc, So when a player makes a challege, they know what they will win or lose

California man is right!! On USCF Live whenever you are playing an opponent you are prompted as to what your rating will be after a win, loss, or draw. ex. win +10, loss -2, draw +3. This way you will know if it is worth it to play your opponent.
The rating system we have here makes NO adjustments for draws what so ever!! No matter how high or low a person is rated against each other. That statement in itself tells us that the rating system we have is inaccurate. I don't know what rating sytem we use...but I know the Glickman sytem works pretty good! Is it possible to switch to this tried and true sytem Fencer?

This is not true. Ratings are calculated even for draws. When I have more time, I can review the algorhitm but I am sure it is correct, I've tested it many times.
However, if you know about a better one and want to help me, give me more details. Everything can be improved.

Fencer,
I would have to agree with the comment that drawn matches do not count. I have had quite a few drawn games. In many cases the difference in ratings was quite a lot (e.g 2000 vs 1300), in which case I would expect to increase the lower rating and decrease the higher rating. NEVER has this occurred. I suspect that there is a defect in the code somewhere causing this.

In addition I would suggest that winning a series 3-2 (which should score 0.6-0.4 where a draw is 0.5-0.5) should score less than winning 5-0. I haven't enough data to tell whether this is the case, but can you confirm that it should be? I suspect that the same piece of code would be used in this case and therefore it may not work either.

If necessary I volunteer to play someone in a game of something where our ratings are dissimilar and engineer a draw to test this hypothesis. Just invite me to a game and alert fencer so he can monitor the ratings.

Just trying to make sure it works!

im not sure to which games you refer too grenv but i know it works with checkers and five in line at least also tank battle works correctly ,other games i havent took any notice ;)

Well I'm referring to chess variations, but it would surprise me if some games worked and others didn't. Anyway a test would work, I have a high rating in some games and am willing to deliberately draw one game against a lower rated player at the risk of losing rating points while the ratings are monitored in order to test.

I'm also sure my rating has not changed after a draw even if there was a big difference in our ratings. This has happened several times, actually i don't think i've noticed my rating changing after a draw even once.

draws have never changed my rating either, which is bloody annoying when you have to battle against a large rating difference in players
