Yes, I will do that:-)

Route Servers are dynamic, they process upto 6000 routing updates a
minute (see http://compute.merit.edu/stats/mae-east/instability).

Route Servers are reconfigured with up to date policy 6 times a day,
i.e. every four hours. Hence, a brand new route registered in IRR may
not be announced by the route servers to the NSPs whose policies are
prefix based for up to at most 4 hours. I think this is what you are
referring to.
