    I usually figure something like 3 or 4 seconds for an expectation value of
    error in delta-T by 2050 using the standard estimated values. In a long-term
    almanac, I would want something that indicates the estimated value of
    delta-T for that year AND provides instructions for amending the tables
    based on the known value of delta-T when that year finally rolls around.
    This is actually a very similar problem to the issue of navigating without
    leap seconds.
