    I finally figured out what you were saying all along. When a client starts
    out with a new saved.state it will find the first point in an average of
    1.4 billion iterations. But this point will only have been iterated an
    average of 1.4 billion/PARAL or about 44 million times. These first points
    will significantly pull down the overall average of the returned points.
    The missing iterations are still in the saved.state file and will bring the
    average back up in the long run.
