    One more suggestion: Run a prediction from the last good elset for a time
    near its epoch. A prediction from the new elset should also be close to
    that "obs", when drag terms are reasonable. If you can't find observations
    over a long arc, you can also use that "obs" as input (unless you suspect
    a maneouvre was made in the interval).
