Rating stability?

How many games do you need to play of a certain style (classic, blitz, bullet, etc.) before your rating at that form is considered stable?

As many games as it takes for rating deviation to drop below the threshold, 110 I believe.

Okay, thanks.

bufferunderrun is right, often it's like 10 games maybe, the rating deviation drops faster if you play players as strong as you or close to that.
