Why did my rapid RD drop so quickly?

Despite the fact that I have only played 9 rapid games, my RD (rating deviation) is incredibly low, with my rating change being at the minimum value: an 8 point change for a win/loss against an opponent with an equivalent rating. And this change happened abruptly; one game, my rating changed by ~50 points, the next, by a mere 9 points.  What gives?

Your rapid RD is 49, which is pretty low. This is just speculation but the site might be using data from other pools to converge RD more quickly.
