Best fit to data (blue line). Reference gradient (red lines):-8.6ms/day/mbar.
Going varies with pressure because of drag, added mass and buoyancy. Barometric compensator fitted 28 March 2010 should fix this.

- ADJUST: +100ms/day to 31150, thanks again Hilary. I have a far-fetched idea that going is proportional to long-term rate-of-change of temperature at -200ms/day per degC/day. This minor adjustment should help test it.
