Rating deviation • page 1/1 • General Chess Discussion • lichess.org

I would to know,how is counted rating deviation?,
I see information that above 110 rating is considered provisional
Is there any method to counted this?

E.g
I have win(105-rating deviation) vs (85,60-rating deviation)=?
I have win(105-rating deviation) vs (102,10)=?
I have defeat(105-rating deviation) vs (65,50-rating deviation)=?

When deviation is decreasing and when increasing?

The general idea is when you play many against opponents with similar ratings (within 100 points of you), your rating deviation decreases. If you play against much lower or much higher rated opponents, your rating deviation increases. Also, there is activity factor. The more time you are inactive the higher is rating deviation.

The exact formulas and calculations in glicko2 system are impossible for an average person to understand. It's much easier to perform calculations in the ELO rating system.

There's a decent explanation of how it works with the complicated mathematics simplified as much as possible here: http://www.englishchess.org.uk/wp-content/uploads/2012/04/The_Glicko_system_for_beginners1.pdf

If you want to get some idea what's going on, that'll be a decent start.

Cheers!
