Do you have any evidence for this assertion?  It seems to me that if
IERS had presented a table in 1980, based on the conventional wisdom
that the earth is continuing to slow down over time, we'd have been
at the edge of that 10-second window in 2000.  And who knows how far
off a 1995 prediction would be in 2015, or what decadal fluctuations
have in store for us in the future.


Anyone have a prediction algorithm in mind, and a result of running it
on the last several decades or centuries of data?
