Yesterday I had about 7000 parties. Recently I've seen my glicko point rapidly fluctuating. Now I already know the reason: all my 7000 parties are gone, and only the last 4 are in the database.
What is going on?
You still have the games. It's just that the site changed 10|0 to rapid instead of blitz

You rating is changing do to your high rating deviation (RD) value in the rapid pool and that will decrease as you play more games within the pool.
