What is the meaning of anything?

The question assumes meaning, where there is none.

In simple terms, your Glicko RD tells you how accurate (or how approximate) your current rating is. An RD of 20 indicates that your rating is correct within 20 points plus or minus, while an RD of 150 indicates a much looser approximation... plus or minus 150 points.

So your Daily rating of 1334 RD 205 means that your rating is only approximate, and that your true playing strength might be anywhere between 1129 and 1539.

The more often you play, the more accurate your rating will be and the lower your RD will drop. And vice-versa: the more seldom you play, the less accurate your rating will be and the higher your RD will climb.

Im only on 877 and ive had a few hundred games .. Won just over half. But here's the thing I saw someones stats earlier who had played less games, had won half but was 100 points and more ahead of me. Apart from playing bad chess I don't know what I'm doing wrong.

 

Any tips would be appreciated guys, in terms of getting better. If anyone wants to have a game and give me pointers I'd be grateful!

Possibly you are confusing "Glicko rating" and "Glicko RD" here.

Find both notions explained at https://en.wikipedia.org/wiki/Glicko_rating_system.

Btw: I just found this in one of Glickman's papers:

The formula for a 95% confidence interval for a player with rating r and ratings deviation RD is given by (r1.96RD, r+ 1.96RD)

which I didn't know. That's pretty much all one needs to know about it.
