Glicko RD Question (Daily Games)

No, this is not a question about the bug that showed up in ratings today.  This is a more general question.

Yes, I understand that as you play more, the rating more accurately reflects you actual skill.  To reflect that, the Glicko RD gradually shrinks from the 350 that a new account gets.  The question I have is:

How many games do you have to play before the Glicko RD drops under 100?  (Obviously, I'm looking for a rough answer.  There are undoubtedly more variables than just number of games.)  My current Glicko RD is 185, with three "real" games completed.  The ones where my opponent timed out before move four probably don't count in that calculation.

There are other factors involved, such as the span of time over which you play those games. Three games in a week will reduce your RD more than three games in three months.

And if you are very consistent about losing to people above you and winning against people below you, it will tighten things up. If you are all over the map in terms of when you win and lose, that will keep it loose.
