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. ------------------------------------------------ Bjorn H.
