    I had a look at the runs I have analyzed separately, and I get
    Run    Total offset
    2529     27.6 cm
    2530     27.6 cm
    2531     27.5 cm
    2535     27.4 cm
    ..i.e. a 2mm change in ~half a days running. This looks pretty small, but
    I guess we should still be careful extrapolating the ZDC offset across
    large time-gaps.
