A quick google throws up plenty of people managing to break 200rpm for a second or two on fast descents and at Rollapaluza. Measured by Garmin or otherwise. Just saying. MIght not be that unrealistic for very short bursts.
EDIT: And given that my earlier post was about me losing control due to descending as fast as I can this explains perfectly why I nearly lost it on my fixed bike. If I am clocked at 200rpm for a second or two on a geared descent, then if I touch that on a fixed with the added effect of gravity no wonder I nearly lost it!
As I say though, I'm not exactly hugely experienced on fixed and genuinely asking if I am being unrealistic.
