    I have plotted the P99 vs Rob's new values for mb and stretch, from
    Gerson's table below (see attachments).
    Rob, can you include these plots on your paper web page so we have
    everything in one place?

    There is a systematic difference between the two papers in both s and
    mb. Most of the points lie either above
    or below the s=s or mb=mb line in the two plots.
