The RD stands for rating deviation. It has to do with the accuracy of which your rating reflects your playing strength. The lower the Glicko RD number, the more likely your rating is close to your playing strength. That’s a very brief explanation. I’m sure others on here could add to it.
Basically the higher your Glicko RD is, the more points you will win or lose in a game.

Right. Glicko RD is just a measure of how approximate (or how accurate) your published rating is. Big numbers mean that your printed rating is just a rough approximation. Small numbers mean that your rating is very close to the actual playing strength.
So there's no such thing as a "good" or "bad" RD.

If I recall that correctly: Assume your rating is R and your Glicko RD is D, then there is a 95% probability that the rating which reflects your actual playing strength is between R-2D and R+2D.
So, if you rating is 1200 and your Glicko RD is 50, your playing strength is higher than 1100 and lower than 1300 with 95% probability.
What is Glicko RD and is it a good thing that I scored 127 in it?
