Well I guess it is almost moot if you are improving but I get the point.  Thanks.

Well, the point is, if you are winning games your rating will not change, which would be very discouraging.

sorry about zborg - very rude of him.

erik,

No offense was taken.  I was being lighthearted in my response.  Unfortunately I realized later that zborg might be a young person.  Actually it was a bad misjudgment on my part.

Let's call it even because this thread has been very helpful to me, Jamie, and I hope others.

I suspect I'm older than @smb.  Yawn.  But he's still competing for the maturity prize.

You can find all your answers at the following--http://www.glicko.net/

Just click on "USCF" and "Glicko" to your heart's desire, as per @NimzoRoy above.

And here's @smb being "lighthearted" --

"If I knew you personally I would show you how men work out disagreements if one of them is not a gentleman." (Direct Quote from Post # 16).

Neat trick, don't you think?  Smile

 o The interval formed by Current rating +/- RD contains your true rating

   with probability of about 0.67.

 

 o The interval formed by Current rating +/- 2 * RD contains your true rating

   with probability of about 0.95.

 

 o The interval formed by Current rating +/- 3 * RD contains your true rating

   with probability of about 0.997.

So the RD does represent a standard bell shaped curve.  The first RD is between -1 and +1 iteration, etc.  Good to know.  Thanks MJ4H!

I need a reality check Jamie.  Was it me or did those dudes have an axe to grind?  I have never met them.  I did open up a can of worms by becoming angry in my first reply which was a mistake.  I have a feeling though that with characters like those no matter what I said I would have been attacked.  

The more important part is that I understand RD better and also how to block people on a blog!  Did you find this tread useful?

Reality check even if I'm not Jamie Wink: No worries, it wasn't you trolling around but according to my experience on all internet forums there are special people always trying to prick around, don't know why. 

On topic: I found this thread useful for my understanding the RD. A little thought about the minimum RD: If the RD reached zero, no further changes in the rating would be possible, wouldn't it? Therefore, you have to set a minimal RD somehow, am I right?

Avatar of MJ4H

RD = 0 would be the same as Elo.  In fact, Glickman says that Elo is basically just a special case of Glicko where all RDs = 0.

Avatar of Spielkalb

Ah, ok, thanks! 

Avatar of smb1959

Thank you Spielkalb, this is my first foray into the mostly positive use of the forum platform. One of my jobs is being a professional counselor so I shouldn't have been surprised about the outliers.

MJ4, as a newcomer, is Elo a rating system that indicates performance in a different way than Glicko?  For example, I believe the NFL and MLB have adopted the Elo formula for pairs like quarterback/receiver or pitcher/batter ratings.  It would seem intuitively somewhat different than Glicko which is a range of "sporting" relationship between the same "positions"--chess player against chess player.  

I guess there comes a point of counting angles on the head of a pin so sorry for asking questions which are far afield of the original topic.
