Are unrated games included in the calculation of Glicko RD?
What causes an RD to rise from 127 to 134? Does playing unrated games against lower rated players cause the RD to rise?
Interesting question. I'd like to know the answer too. Of course there's nothing to lose with a rising RD.
Your RD is supposed to be a measure of how well you rating reflects your true chess playing ability, or how close it is to being accurate. So if you play a lot of people with high RD's then yours could rise because winning or losing to someone else whose rating may be far from accurate does not prove anything. Also, RD can rise over time with inactivity.
There are better explanations out there I am sure.
I believe unrated are just that...un(not)rated. They don't count for or against your RD at all.
