    keyword=feedback software version rolled back

    The feedback software (panFFB) version was rolled back to attempt to stop
    the now-frequent feedback hangups. This old version does not update
    every 2 minutes, unless the charge asymmetry is more than 2 sigma from
    zero OR less than 10 ppm. Therefore an out-of-date timestamp will not
    mean that feedback is hung, unless the charge asymmetry is large (>
    2sigma) or small (<10ppm).

    Even with this odd behavior, charge asymmetry will always remain
    below 100 ppm while feedback is functioning.
