From a single data point on my router, /24's currently account for 64% of

prefixes.  It doesn't appear to me there is a significant difference
between flap behaivor of long prefixes and short prefixes.  There are
more long prefixes than short prefixes.  But as a group they both tend
to flap the same proportion of 2% of the routes within the group.

Sorry, I'm not convinced this is the case. There is not enough
empirical evidence.
